Scientific Errors in the Quran: Difference between revisions

If the [[Qur’an]] contains even one [[Contradictions and Errors|contradiction]] or mistake then the claims of divine authorship and infallibility are not true. An objective evaluation of the Qur’an shows that it contains numerous [[Islam and Science|scientific]] and historical errors and reflects a pre-scientific, 7^th century view of the natural world.

Some will contest these numerous errors in the Qur'an by appealing to metaphor, alternative meanings, or [[w:Phenomenology (philosophy)|phenomenological]] interpretations of the text. Even supposing alternative explanations were possible in every case, the problem would remain that the Qur’an contains no obvious attempts to differentiate its understanding of the natural world and historical events from the common folklore and unscientific misconceptions of the people living in 7^th century Arabia. An all-powerful, all-knowing, perfect communicator would have been able to foresee how such misleading statements would be understood by future generations and the doubts and confusions they would cause. Such overwhelming weakness in the Qur'an when we should expect perfection is already reason enough to reject any claims to its divine authorship.

Some try to explain away the above Qur'anic description of the sun moving in an orbit as a reference to our sun orbiting the black hole at the center of the milky way galaxy every 225 million years. This is an [[w:Ad hoc hypothesis|Ad hoc hypothesis]], of no relevance to human time scales, and nothing from the text implies that the sun is orbiting anything other than the Earth. If the author had knowledge of the sun orbiting a black hole then it is conspicuous that he never mentions it explicitly nor in any way differentiates the sun's orbit from that of the moon.  

Notice also that the sun running / pursuing its course ([http://www.studyquran.org/LaneLexicon/Volume2/00000051.pdf yajree] يَجْرِىٓ) is something that the author expects people to have seen (another problem for the galactic orbit interpretation).  

The [http://www.studyquran.org/LaneLexicon/Volume1/00000350.pdf Arabic word] translated "follow" is primarily defined as to follow, go or walk behind, follow in way of immitation, of action etc. and was often used for animals like camels following behind each other. Yet the Moon does not actually follow behind the sun's movement, nor does it provide its own light like the sun. The verse is most suggestive of a worldview in which the moon and sun traverse the same or similar paths after one another, which is what a 7th century person might believe from observing the sky. A less suspicious choice of word would have been better for a supposedly perfect book if it merely meant the sun and moon appear one after the other. One day instead of following the sun, the moon will by joined with it according to another verse (see the [https://wikiislam.net/index.php?title=Scientific_Errors_in_the_Quran&stable=0#The_similar_size_and_distance_of_the_sun_and_moon Similar Size and Distance of the Sun and Moon] section below).

Here the Qur'an quotes a few lines from a debate between Abraham and a disbelieving King, where Abraham replies that Allah 'brings the sun' (yatee biashshamsi يَأْتِى بِٱلشَّمْسِ) from the east. The arabic verb and preposition indicates that the sun actually moves. The verb means [http://www.studyquran.org/LaneLexicon/Volume1/00000052.pdf to come], and when it has an object with the bi preposition it means to bring, as in many other instances in the Qur'an. While the story is quoting a mere human's words, the author clearly believes it to be a good response and sees no problem with it.

Centuries after Muhammad lived, people with better astronomical knowledge had to invent creative interpretations of these verses such that Dhu'l-Qarnayn only traveled until he reached "the west" or to a spot "at the time" when the sun set and not the "place" where the sun set. Unfortunately, these alternative interpretations are severely undermined by the [[Dhul-Qarnayn_and_the_Sun_Setting_in_a_Muddy_Spring_-_Part_One#First_interpretation:_He_reached_the_west_and_east|context and Arabic words]] used in these verses, which instead point to physical locations where the sun did its setting and rising. Plenty of evidence shows that the early Muslims understood the verse in this straightforward way. Again, we must ask why an all-knowing being would use such misleading verses that mimic the misconceptions and legends prevalent at the time if one of the alternative explanations is correct.

Secondly, neither the universe nor Earth were formed in six distinct long periods of time. It would have been trivial for an all-knowing diety to have poetically indicated the vast duration in which the universe has developed, which has taken place over the past [[w:Age of the universe|13.8 billion years]].

The author of the Qur'an is also unaware that the [[w:Abundance of elements in Earth's crust|elements in the Earth's crust]] and core were first formed in stars by [[w:Nucleosynthesis|nucleosynthesis]]. When those stars exploded as [[w:Supernova|supernovas]], they expelled the elements that were used in future solar systems such as our own. Modern radiometric dating of meteorites and rocks from the Earth and Moon show that these bodies were formed at the same time as the sun and its other planets, [[w:Age_of_the_Earth|4.5 billion years ago]]. Yet the Qur'an describes the Earth being fully formed before the stars.

The word lamps (masabeeha مَصَٰبِيحَ) in {{Quran|41|12}} and {{Quran|67|5}} with which Allah adorns (zayyanna زَيَّنَّا) the lowest heaven would obviously have to include any luminous bodies such as the stars, as does kawakibi (كَوَاكِبِ) in {{Quran|37|6}}, a word that also appears in Joseph's dream ({{Quran|12|4}}) and the destruction of the heavens ({{Quran-range|82|1|2}}). Heaven is similarly adorned (same verb) with zodiacal constellations / great stars (baroojan بُرُوجًا) in {{Quran-range|15|16|17}}.

Some websites attempt to reconcile the Qur'anic description with modern science by denying that the word 'Then' in the verses above indicate sequence, and instead claim that it means 'moreover'. They claim this despite the fact that these words (thumma in 41:11 and 2:29, and fa in 41:12 - all translated as 'Then') generally are used to indicate sequence. In other contexts thumma was sometimes used to mean 'moreover', which is generally clear from those contexts, but the passages quoted above describe a process - the creation of the heavens and Earth, and it would be ludicrous to use these words when describing such a process if they were not indicating sequence.

Some websites claim that the following verse is compatible with the [[w:Big Bang|Big Bang]] theory. But according to this theory, the Universe was formed about 13.8 billion years ago due to a [[w:Chronology of the universe|rapid expansion]] from singularity. The earth was formed 4.54 billion years ago from [[w:History of the Earth|accretion]] of debris that surrounded the precursor of the Sun. There was no "separation" of the "joined" earth and heavens as this verse suggests. It is, in fact, a repetition of [[w:World egg|cosmic egg]] myths in which an egg-like structure was split into two halves, the lower half forming the earth and the upper half forming the heaven. The verse itself assumes that the listeners are familiar with the concept.

Moreover, the very next verse {{Quran|21|31}} speaks of mountains being placed on the Earth. Here 'the Earth' clearly means an actual world, so how do the Islamic websites expect anyone to believe that in the previous verse 'the Earth' refers merely to atomic particles at the time of the big bang that would billions of years later form the Earth?

Apologetics that try to reinterpret 'smoke' as the primordial state of the universe after the big bang should notice (aside from their poor grasp of science) that the Qur'an indicates a time when just the heaven, but not Earth is smoke. Furthermore, the Earth and its mountains are clearly mentioned as already existing in the previous two verses ({{Quran-range|41|9|10}} discussed above).

The number, like seven heavens, might have come from a misunderstanding of mythology from classical antiquity in which there were seven moving planets (Mercury, Venus, Mars, Jupiter, Saturn, the sun and moon). If instead we take it to mean seven actual planets the Qur'an is still wrong. According to astronomers, there are eight ordinary planets and five dwarf planets, which leaves the grand total at thirteen in our solar system. Modern astronomy also has found thousands of other planets in other solar systems and Cosmologists estimate that hundreds of billions of stars and planets exist in the universe. The author of the Qur'an singling out such a small number of celestial objects only reaffirms his ignorance of the makeup of the universe.

Some Islamic websites claim that these are seven layers of the atmosphere, despite the fact that verse 37:6 says that stars are in the nearest heaven. There are only 5 not 7 principal layers to the [[W:Atmosphere of Earth|Earth's atmosphere]], and likewise only 5 not 7 major layers to the Earth itself.

The word translated "are joined" is Arabic [http://www.studyquran.org/LaneLexicon/Volume2/00000091.pdf jumi'a], a verb which means to collect together, gather together, bring together. Given that this would actually require the moon to travel 98 million miles away from Earth and into the sun, which dwarfs it by over 600 times in diameter, it seems vastly less fitting as an apocalyptic event than if the ancient conception of the cosmos was correct. Thus it is far more likely that the author had such a misconception about the sun and moon.

The author of the Qur'an does not seem to know the difference between stars (giant balls of gas thousands of times larger than the earth) and meteors which are small rocky masses of debris which brighten up after entering the earth's atmosphere. Many ancient people confused the two, as meteors look like stars that are streaking across the sky; this is why they were often called [[w:Meteoroid|shooting stars]] or falling stars. In the following verse, the Qur'an claims that Allah uses stars as missiles to ward away devils. This repeats a common Arab myth at the time the Qur'an was first recited.

The same Arabic words are used at the start of verse 67:5 as in 37.6 (زَيَّنَّا ٱلسَّمَآءَ ٱلدُّنْيَا), except the stars are described as lamps. Clearly the lamps that 'beautify the heaven' refer to stars (and perhaps also the 5 visible planets), which are always there. Meteors are generally not much larger than grains of sand and are only visible for a second when they burn up, generating light in the Earth's atmosphere after millions of years in darkness, but the author of the Qur'an believes that meteors (the 'missiles') are a kind of star.  

A common myth at the time of the Quran's composition was that the sky or heavens were held up with pillars. Many Bedouin people living in Arabia imagined the sky as a large tent covering, similar to the tents they used. The author repeats this myth by describing the sky as being "raised" above the earth.

The Qur'an author thought that the sky/heaven is like a ceiling held up by Allah that can fall to earth or fragments break off and fall on someone. This is obviously impossible as the earth's atmosphere is simply made of gas and outer space is not a solid object.

The Qur'an says that the stars will fall ([http://www.studyquran.org/LaneLexicon/Volume7/00000124.pdf inkadarat] ٱنكَدَرَتْ) along with other dramatic events surrounding the last day. The author clearly had no idea of the size and distance of the stars. The word كدر in the form used in this verse (form VII) meant to dart down as is said of a bird or hawk, or to fall and scatter.

In polar regions, the longevity of day and night vary during summer and winter. The day gets shorter and shorter in winter until there are days or weeks of uninterrupted night. At the poles themselves, day and night alternately last for six months and all phases of the moon occur several times between sunrise and sunset. The author of the Qur'an did not know about this and he only repeated earlier geocentric ideas. See also the [https://wikiislam.net/index.php?title=Scientific_Errors_in_the_Quran&stable=0#Fasting_and_Prayer_Requirements_Near_the_Poles Fasting and Prayer Requirements Near the Poles] section below.

Furthermore, when reading this verse one should wonder in what sense day and night each have an orbit. See [[Geocentrism and the Quran]] regarding that question.

The Qur'an and Hadith depict that humans are formed from a clot of blood after an initial semen stage. There is no stage in embryonic development where humans are formed from a clot of blood. This description is likely influenced by an unscientific and primitive understanding of human reproduction based on observations from an early-term miscarriage and a woman's menstrual cycle. While in modern times some Muslims seek to use alternative meanings for the relevant word, the mere fact that it certainly can mean clotted blood (which is the unanimous interpretation in the classical tafsirs), in a passage about a biological process (formation of a baby), is a major weakness in what should be a perfect description.

The Qur'an states that milk is produced, in the body, somewhere between excretions and blood. The mammary glands, where milk is produced and stored, are nowhere near the intestines which is where excrement is stored. Many kinds of cattle and goat milk needs processing or pasteurization before they can safely be consumed; the milk is often infected with bacteria and other micro-organisms. A significant number of  humans are [[Qur'an and Milk|lactose intolerant]] and unable to digest milk without experiencing abdominal bloating and cramps, flatulence, diarrhea, nausea, or vomiting. This makes the Qur'anic claim that milk is 'pure' and 'agreeable' to those who drink it dubious.

The Qur'an tells all Muslims to face in the direction of the Kaaba in Mecca when they pray. However, even if you suppose that alligning yourself with a great circle around the globe counts as facing the direction of Mecca, you are simultaneously facing opposite its direction as the circle can be traced behind you. Even worse, on the opposite side of the Earth every direction is equally facing towards and away from Mecca. The Americas are mostly in the hemisphere of this antipode. There, the rhumb line method is often preferred because the great circle method lines across the continent diverge before they start to converge when they enter the hemisphere of Mecca, causing people north and south to face away from each as they pray. Astronauts in Earth orbit or (one day) on the Moon and Mars would require even more contrived solutions. The author here presupposes a small world, local to Arabia, that is flat. Only in that world view can people everywhere face Mecca.  

The Qur'an commands Muslims to fast from eating and drinking from sunrise till sunset during Ramadan. The author of the Qur'an was apparently unfamiliar with the polar regions in which there are six months of sunlight and six months of perpetual night during Summer and Winter. Such fasting is not observable by anyone living in the polar regions, and very easy (depth of Winter) or extremely hard (height of Summer) in places within around 40 degrees latitude of the poles. Various contrived rules have been proposed by Muslim scholars for those at such latitudes to try to accommodate the inconvenient fact that we live on a round Earth.

A similar issue exists for the five daily prayers. Anyone living in the polar region would not be able to make a sunset or sunrise prayer for much of the year. Even for cities further south like Aberdeen in Scotland, the gap between the night prayer (Isha) and the dawn prayer (Fajr) is around 4 and a half hours in June, so anyone following these rules has to interupt their sleep around 3.20am, then go back to sleep before getting up for the day. Such issues would not have crossed the mind of a 7th century man in Arabia, who believed that everyone experiences sunrise and sunset when he does, and where it would be perfectly natural to arise at dawn any time of the year.

The author of the Qur'an mentions to his audience that the Earth is 'spread out' and layed flat. The arabic word here ([http://www.studyquran.org/LaneLexicon/Volume4/00000081.pdf sataha]) was used to describe making the flat top or roof of a house or chamber and making a top surface flat. Words from the same root mean the flat top surface or roof of a house or chamber, a flat plane in geometry, a level place upon which dates can be spread, a rolling pin (which expands the dough), plane or flat.

The Qur'anic commentary of al-Jalalayn agrees with this understanding of the verse saying that most scholars at his time agree that the earth is flat and not spherical.

Some of the highest death tolls from natural disasters in the last decade were in Muslim countries. In fact, natural disasters do not differentiate between Muslim or non-Muslim nations nor are they controlled by a divine being. Earth quakes are extremely common along tectonic fault lines and are not a punishment for human behavior but the byproduct of natural forces. The Qur'anic author perpetuates an unscientific understanding of his phenomena in there verses.

Two of the deadliest blizzards in history happened in Muslim countries. However, the Qur'an regards those natural disasters as violent punishment from God. Weather patterns follow predictable patterns and are not controlled by a divine being.  

Every verse about rain in the Qur'an implies that rain comes either directly from the sky or from Allah. However the crucial step of evaporation of water into the air is conspicuously never mentioned, despite apologetics claiming that the water cycle is described in the Qur'an. Condensation of water is never mentioned. This means that the author of the Qur'an believed in clouds and rainfall as a linear process orchestrated by Allah as opposed to a cyclic process.

Tafsirs such as Jalalayn and the one attributed to Ibn Abbas say that this means mountains in the sky. Ibn Kathir notes two views, that these are literally mountains of hail in the sky, or that they are a metaphor for clouds. Clouds could poetically be described as mountains in the sky, but for the verse to literally say "mountains of hail in the sky" strongly suggests large masses of ice (in the clouds or otherwise), and we can see it being understood in this literal way as evidenced in tafsirs.

The Qur'anic author was superstitious about thunder and lightning and imagined that they strike those whom Allah wishes to smite.

Ants typically communicate with each other using pheromone which are a chemical signal. While scientists have also discovered that ants make some noises, nothing has ever indicated that the brains of ants could produce such complex communication as is depicted in the Quranic story of Solomon and the ants. However, the Qur'an tells us that not only does an ant warn her fellow ants of the approach of a large army of humans, but it recognizes one of the humans as Solomon. Then, he also understands her speech. How an ant could even see that far or have known the identify of Solomon is never explained. This account of a talking ant is clearly a legend and not scientific.

It took thousands of years of domestication and cross-breeding before horses were domesticated approximately 4,000 years ago in East Europe and Central Asia. Prior to this, horses were wild animals though the Qur'an neglects to mention this important fact. Even today [[w:Feral horse|feral horses]] are descendants of once domesticated horses that aren't tamed or used for human transportation.  

Today, engineers and scientists are well aware of the aerodynamic properties of a bird's wing. It functions by creating a difference in the air pressure between the lower and upper part of the wing and this creates lift that pushes the bird upward. The wings of birds evolved over millions of years to acquire this feature. The author of the Qur'an, however, is unaware of these scientific details and says that 'nothing' holds up the bird except the miraculous power of Allah.

Islamic websites try to escape the embarrassment that the Qur'an contains an un-historical, world-wide flood story as found in the Bible and ancient near-Eastern mythology. They claim instead that the textual evidence supports nothing more than a regional flood in the Qur'anic story of Noah. There are many severe weaknesses in this claim.

If the flood was not world-wide then why was Noah instructed to spend time building a boat at all when he could have just taken his family out of the flood region with sufficient warning? Animals in the region could have done likewise by the same kind of miracle needed to bring them all to an ark.  

The story of Noah was a [[w:Flood myth|famous myth]] of a ''world-wide'' flood. At very least it is a major weakness that the Qur'an makes no attempt to distinguish itself from the same world-wide flood myth that its listeners were familiar with.

However, it is incumbent upon Muslims to pray in Arabic, recite the Qur'an in Arabic, and understand commentaries and the traditions of Muhammad in classical Arabic. We are left wondering why an all-knowing being would not provide a more efficient way to send his message to all people on earth and why he does not account for the immense diversity of languages.
