|Garbha Upinandas (Hindu text)
|"From the conjugation of blood and semen the embryo comes into existence. During the period favorable to conception, after the sexual intercourse, (it) becomes a Kalada (one-day-old embryo). After remaining seven nights it becomes a vesicle. After a fortnight it becomes a sperical mass. After a month it becomes a firm mass".<ref>Journal of Mammalian Ova Research - [http://www.bioone.org/doi/abs/10.1274/jmor.26.2?journalCode=jmor History of the Egg in Embryology] - 26(1):2-9. 2009

You clothed me with skin and flesh, and [inside me] did you interweave bones and sinews."<ref>[http://www.biblegateway.com/passage/?search=Job+10%3A8-11%2CJob+31%3A15&version=NIV Job 10:8-11] - BibleGateway</ref>

2nd stage: "The seed (embryo), then, is contained in a membrane ... Moreover, it grows because of its mother's blood, which descends to the womb. For once a woman conceives, she ceases to menstruate..."<ref>Section 14, p. 326</ref>
3rd stage: "At this stage, with the descent and coagulation of the mother's blood, flesh begins to be formed, with the umbilicus."<ref>Section 14, p. 326</ref><BR>4th stage: "As the flesh grows it is formed into distinct members by breath ...

The vessels join to the uterus like the roots of plants, and through them the embryo receives its nourishment".<ref>Aristotle, De Generatione Animalium, Book II, 740a28-740a35, as per Barnes, opere citato, p. 1149</ref>

|Claudius Galenus
|"let us divide the creation of the foetus overall into four periods of time.<BR>''The first'' is that in which. as is seen both in abortions and in dissection, the form of the semen prevails [Arabic nutfah]. At this time, Hippocrates too, the all-marvelous, does not yet call the conformation of the animal a foetus; as we heard just now in the case of semen voided in the sixth day, he still calls it semen. But when it has been filled with blood [Arabic alaqa], and heart, brain and liver are still unarticulated and unshaped yet have by now a certain solidarity and considerable size,<BR>this is ''the second period''; the substance of the foetus has the form of flesh and no longer the form of semen. Accordingly you would find that Hippocrates too no longer calls such a form semen but, as was said, foetus.<BR>''The third period'' follows on this, when, as was said, it is possible to see the three ruling parts clearly and a kind of outline, a silhouette, as it were, of all the other parts [Arabic mudghah]. You will see the conformation of the three ruling parts more clearly, that of the parts of the stomach more dimly, and much more still, that of the limbs. Later on they form "twigs", as Hippocrates expressed it, indicating by the term their similarity to branches.<BR>''The fourth and final period'' is at the stage when all the parts in the limbs have been differentiated; and at this part Hippocrates the marvelous no longer calls the foetus an embryo only, but already a child, too when he says that it jerks and moves as an animal now fully formed."<ref>Corpus Medicorum Graecorum: Galeni de Semine (Galen: On Semen) (Greek text with English trans. Phillip de Lacy, Akademic Verlag, 1992) section I:9:1-10 pp. 92-95, 101</ref>
"... The time has come for nature to articulate the organs precisely and to bring all the parts to completion. Thus it caused flesh to grow on and around all the bones, and at the same time ... it made at the ends of the bones ligaments that bind them to each other, and along their entire length it placed around them on all sides thin membranes, called periosteal, on which it caused flesh to grow."<ref>Corpus Medicorum Graecorum: Galeni de Semine (Galen: On Semen) (Greek text with English trans.

|Talmud (Jewish text)
|The embryo was called peri habbetten (fruit of the body) and develops as:
 
1. golem (formless, rolled-up thing);<BR>
2. shefir meruqqam (embroidered foetus - shefir means amniotic sac); <BR>
3. 'ubbar (something carried); v'alad (child); v'alad shel qayama (noble or viable child) and <BR>
4. ben she-kallu chadashav (child whose months have been completed).<ref>Samuel ha-Yehudi</ref>

|Muhammad ibn ‘Abdullāh
|“Allah's Apostle, the true and truly inspired said, "(The matter of the Creation of) a human being is put together in the womb of the mother in forty days, and then he becomes a clot of thick blood for a similar period, and then a piece of flesh for a similar period.”<ref>{{Bukhari|4|54|430}}</ref>
“The Prophet said, "Allah puts an angel in charge of the uterus and the angel says, 'O Lord, (it is) semen! O Lord, (it is now) a clot! O Lord, (it is now) a piece of flesh.' And then, if Allah wishes to complete its creation, the angel asks, 'O Lord, (will it be) a male or a female?”<ref>{{Bukhari|8|77|594}}</ref><BR>"Verily We created man from a product of wet earth; Then placed him as a drop (of seed) in a safe lodging; Then fashioned We the drop a clot, then fashioned We the clot a little lump, then fashioned We the little lump bones, then clothed the bones with flesh, and then produced it as another creation. So blessed be Allah, the Best of creators!"<ref>{{cite Quran|23|12|end=14|style=ref}}</ref>

In conclusion there is not a single statement contained within the [[Qur'an]] or [[hadith]] literature relating to modern embryology that was not well known through direct observation by the ancient Greek and Indian physicians many centuries before the Qur'an was ever "revealed". Morever, much of what the Qur'an actually does contain pertaining to embryology is scientifically inaccurate.
