Did Muhammad and the Earliest Muslims know the Earth is Round?

Introduction

When critics point out that the Qur'anic Earth is flat, or that the author of the Qur'an believed that the sun sets in a muddy spring, and furthermore, that such verses encouraged the early Muslims to maintain false beliefs about the world, sometimes people claim in response that everyone knew that the Earth was round by the time of Muhammad. This article will dispel that assertion, and as such is complementary to discussions about Islamic cosmography.

It seems that despite the best efforts of apologetics websites, there is no known evidence for a round Earth belief among the earliest Muslims, which would surely be abundant if Muhammad had such knowledge, and plenty of evidence for belief in a flat Earth.

False claims that there was always a Muslim consensus for a round Earth

While many people in some regions had known for centuries that the Earth was round and not flat, the question is whether Muhammad and his nearby contemporaries in Arabia had this knowledge.

One Islamic fatwah website (copied by others) quotes from scholars who lived hundreds of years after Muhammad in a failed attempt to show that there was always a Muslim consensus that the Earth is round. They are implying that the Qur'an does not reflect a very human lack of knowledge about the shape of the Earth.

ibn Taymiyyah

To do so, they first quote from a book by ibn Taymiyyah (d. 728 AH/1328 CE), who in turn cites Abu’l-Husayn Ahmad ibn Ja‘far ibn al Munadi as saying that the scholars from the second level of the companions of Imam Ahmad (d. 241 AH / 855 CE) – i.e. the early Hanbalis – said there was consensus among the scholars that both heaven and Earth are balls, the latter based on astronomical reasoning. This evidence is worthless, because from the 8th century CE the Muslims had access to Greek and Indian astronomical knowledge (see below), so of course Muslim scholars had this view. The term 'consensus' (ijma) was used in different ways by different scholars, but essentially meant the agreement of Muslim scholars, or ideally, also of the salaf (the first three generations of Muslims)^[1]. In this case it is explicitly the scholars. As we read on, however, it is apparent that even this "consensus" for a round Earth was rather nebulous, and as already mentioned and will see again, those who did endorse a round Earth did so because they were educated people aware of the astronomical arguments.

They then quote ibn Taymiyyah again, who is answering a question about the shape of the heavens and Earth, this time citing Abu’l-Husayn Ahmad ibn Ja‘far ibn al Munadi (again), Abu’l-Faraj ibn al-Jawzi (d. 597 AH / 1201 CE), and ibn Hazm (d. 456 AH / 1064 CE) as saying that there is a consensus that the heavens are round. Notice that despite the topic, he says the heavens, but nothing about the Earth. He says they provided evidence from the Qur'an, sunnah, and narrations from the companions (sahabah) and second generation.

Ibn Taymiyyah continues the passage^[2] giving the supposed evidence for round heavens in the Qur'an, sunnah, and narrations from the early Muslims (not included by the Islamic fatwah website). In between, he argues that a round heavens and Earth is supported by what specialists on tafsir and language have said about certain words in the Qur'an.

It is the hadiths and companions that we are interested in for the purposes of this article (the Qur'an verses cited by ibn Taymiyyah are Quran 21:33, Quran 36:40, Quran 39:5, and Quran 67:5).

Narrations of the companions

The solitary piece of evidence that Ibn Taymiyyah can bring from the companions about round heavens is that ibn 'Abbas and others said regarding Quran 36:40 and the heavenly bodies swimming in a falak (rounded course):

See the comments and footnotes about falak in the article Geocentrism and the Quran (a whirl was a small wheel or hemisphere that span around a spindle^[4]). Now given that the sun and moon appear both to arc across the sky, even to those who imagined the Earth was flat and the heavens a dome (or a sphere), such people would also imagine some path for them continuing beneath the Earth after they have set so they can return whence they came (as also in the hadith from Abu Dharr discussed later in this article). Indeed, this is precisely what we read from ibn 'Abbas as noted by ibn Kathir in his Tafsir for Quran 31:29. The sun runs in its falak (فَلَكهَا) in the sky / heaven (السَّمَاء) during the day, and when it sets it runs during the night (بِاللَّيْلِ - omitted from the translation) in its falak beneath the Earth:^[3]

So the evidence from the companions presented by ibn Taymiyyah is not exactly much to go on regarding the shape of the heavens, and says nothing about the shape of the Earth.

Hadiths

Ibn Taymiyyah then mentions the hadith in Sunan Abu Dawud (graded weak) (Sunan Abu Dawud 41:4708) in which Muhammad forms a dome with his fingers above his head when saying that Allah's throne is above the heavens. Ibn Taymiyyah's interpretation is that the throne is dome shaped.

The other hadith he mentions is in Sahih Bukhari, which says:

Ibn Taymiyyah then says that a middle only exists in a round thing. How any of this helps demonstrate that the heavens are spherical is a mystery.

Ibn Hazm

The Islamic fatwah website then quotes one of the three that ibn Taymiyyah cited, ibn Hazm, who said that there is sound evidence that the Earth is round, but the common people and some non-leading Muslim scholars thought otherwise, though none of the leading scholars denied that the Earth is round.

So firstly, uneducated people (as were Muhammad and the sahabah) thought the Earth to be flat even in ibn Hazm's day. Secondly, his statement provides no evidence that the earliest scholars actually said the Earth is round (just that leading scholars didn't say it was flat). It is clear that Ibn Hazm and the other followers of Imam Ahmad ibn Hanbal mentioned above believed in a round Earth for astronomical reasons, even if some of them attempted to find further backup from the Qur'an and sunnah.

Given that Ibn Taymiyyah cites these scholars, the narrations he then uses to support spherical heavens (when asked about the shape of both the heavens and Earth), were presumably the best they could come up with. If a consensus for a round Earth went back to Muhammad and the companions, surely the scholars could come up with better than this feeble evidence.

Even the already dubious claims of just a scholarly consensus are further undermined when we read Tafsir al-Jalalayn, which was written centuries later by two people who were not trying to massage the Qur'an to fit a round Earth reality. For Quran 88:20 we read the following:

For details on this word, sutihat, in verse 88:20, see this section of the flat Earth article.

The website goes on to quote from a 20th century book of fatwas, which claims that the Earth is egg shaped and also makes an argument using verse 39:5, both of which are debunked in the article Flat Earth and the Quran.

So to summarise, there seems to be no evidence available that the earliest Muslims believed the Earth is round. Instead, there is lots of evidence that they thought the Earth to be flat, as explained further below. But before we come to that, let's see what historians have to say about Arab astronomical knowledge.

Acquisition of Greek and Indian astronomical knowledge

Ptolemy’s Almagest was translated into Arabic in the 8^th century CE after the Qur’an was completed. Ptolemy recorded in book five of his AlMagest in the mid-2^nd century CE the discovery of Hipparchus, and of Aristarchus before him, that the sun is much larger than the earth and much more distant than the moon, and the Aristotelian view that Earth was spherical and the heavens were celestial spheres.^[5]

Professor Kevin Van Bladel says:

Earlier in the same paper, Van Bladel describes how Christian theologians in the region of Syria in the sixth century CE shared the view that the Earth was flat and the heaven, or series of heavens was like a dome or tent above the Earth, based on their reading of the Hebrew and New Testament scriptures. This was a rival view to that of the churchmen of Alexandria who supported the Aristotelian-Ptolemaic view of a spherical Earth surrounded by spinning celestial spheres. See the footnote below^[7] for excerpts of that chapter, which he summarises by saying:

David A. King writes:

Hoskin and Gingerich say:

Flat Earth(s) in hadith collections

The next few sections are about evidence of a commonplace flat Earth belief among the earliest Muslims (it omits evidence from the Qur'an itself, as per the purpose of this article stated in the introduction).

Two easy ways to demonstrate that at least a large number of the earliest Muslims imagined the Earth to be flat are to look at hadiths and tafsirs. For the purposes of this article, it matters little whether the hadiths are authentic or not; either way they demonstrate beliefs of early Muslims.

This next hadith is on the same topic. It is graded daif (weak), but shows what some early Muslims (if not actually Muhammad) thought about the world:

Notice that it says, "from its rising place" (min matli'iha مَطْلِعِهَا ), and "from the place of your setting" (min maghribiki مِنْ مَغْرِبِكِ). The sun is commanded to go somewhere – it cannot be claimed that this is an idiomatic way of commanding the Earth to rotate, nor that the words mean the east and west here (despite mistranslations of similar hadiths), not least because the words al mashriq and al maghrib would have been used for that purpose and without the possessive suffixes. The words used in this hadith must refer to the sun’s rising and setting places - it is pure nonsense to claim otherwise.

Flat Earth in Tafsirs

The spring where the sun sets

In the tafsir of al-Tabari (b. 224 AH / 839 CE) for Quran 18:86, we see the following remarks about the nature of the spring into which the sun sets. The similar sounding words hami'ah (muddy) and hamiyah (hot) seem to have become confused at some point:

So he says of the Basra version:

"بـمعنى: أنها تغرب فـي عين ماء ذات حمأة"

"Meaning: that it sets in a spring of muddy water."

And of the people of Kufa reading hot spring:

"يعنـي أنها تغرب فـي عين ماء حارّة"

"It means that it sets in a spring of hot water"

He goes on to quote various opinions such as Ibn 'Abbas, that the sun sets in black mud:

From these comments and narrations in al-Tabari's tafsir, we can reasonably conclude that many, and perhaps all, of the earliest Muslims took verse 18:86 to mean that the sun actually sets in a spring and thus that the Earth is flat.

If the reader wishes to explore this sub-topic further, they can see how al-Tabari in his History of the Prophets and Kings, and al-Baydawi in his tafsir mention the opinion that the sun has 360 springs into which it can set, and the pre-Islamic Arab poems on the same topic in the article Dhu'l Qarnayn and the Sun Setting in a Muddy Spring.

The sky is a dome above the Earth

In his tafsir for Quran 2:22, al-Tabari includes narrations from some of the earliest Muslims about the sky being a dome or ceiling over the Earth:

Ibn Kathir in his tafsir for Quran 13:2 has yet more narrations of the sahabah and tabi'un (2nd generation) on this topic:

The Earth on the back of a whale

Al-Tabari's tafsir contains other indications of a common flat Earth belief. For example, regarding Quran 68:1, which mysteriously starts with the Arabic letter nun, he (and many other tafsirs) records that one of the interpretations among sahabah such as ibn 'Abbas was that the 'nun' is a whale on whose back the Earth is carried (other interpretations were that it was an inkwell, or a name of Allah). The evidence is extensively documented on other websites including narrations with sahih chains from the sahabah, so the interested reader is referred to them.^[12][13][14]

Conclusion

Islamic apologists have failed to provide any evidence that Muhammad or the earliest Muslims knew that the Earth was round. In contrast, there is lots of evidence to show them believing the Earth to be flat.

This evidence can be used as a foundation for other arguments concerning the flat Earth verses in the Qur'an, that they cause a justifiable suspicion that the author of the Qur'an was just as unaware as his nearby contemporaries about the shape of the Earth. It can also be used to make the point that it is a secondary major weakness of the Qur'an to use such language when it will inevitably encourage 7th century Muslims to maintain their false notion that the Earth is flat (and indeed for many centuries later for some Muslims, such as al-Suyuti in his Tafsir al-Jalalyn, and ibn Kathir in his Tafsir^[15]).
