Embryology In The Quran by Hamza Andreas Tzortzis

The next stage of human development defined in the Qur’an is mudghah. This term means to chew, mastication, chewing, to be chewed, and a small piece of meat.61 62 It also describes the embryo after it passes to another stage and becomes flesh.63 Other meanings include something that teeth have chewed and left visible marks on; and marks that change in the process of chewing due to the repetitive act.64 The mudghah stage is elaborated on further, elsewhere in the Qur'an:

then from a fleshy lump (mudghah), formed and unformed. 65

The Arabic word used here for ‘formed’ is mukhallqah which can also mean ‘shaped’ or ‘moulded’.66

Taking a lexical approach to the interpretation of the word, this stage deals with the 4th week, when somites, which resemble tooth-marks [see Figures 5 and 6], begin to develop. The appearance of the embryo at this stage, due to somite development, corresponds with the meanings: ‘to be chewed’ and ‘something that teeth have chewed and left visible marks on’. Concerning somite development, Barry Mitchell and Ram Sharma write:

In the fourth week, the medially placed mesenchymal cells of the somites migrate towards the notochord to form scelerotomes [mesenchyme is the loosely arranged embryonic connective tissue in the embryo].67

Another meaning for the word mudghah includes something looking like a morsel of flesh. This too is an accurate description of the embryo's appearance at this stage. Interestingly, the qur’anic explanation of mudghah as being “formed and unformed”, can refer to the organogenetic period, during which all the main organs have begun to develop, but are not yet fully formed.68 This period also occurs at around the 4th week

An argument raised by critics concerning the mudghah stage is that a chewed piece of meat or a lump of flesh does not resemble the embryo at any stage described by modern embryology. In responding to this, it is necessary to clarify what constitutes a ‘chewed piece of flesh’. It includes, not just mastication, but also something being chewed just the once. This maintains the meaning of the word mudghah as the bite marks do resemble a piece of meat chewed once. This is highlighted by its other meaning: ‘something that teeth have chewed and left visible marks on’.

The `mudghah stage:

The development of somites giving the embryo the appearance of a chewed substance. What looks like a morsel of flesh - an accurate description of embryo's appearance at this stage.

It also describes the organogenetic period (the development of organs, not yet fully formed).

As ever, there have been attempts to compare the qur’anic term mudghah with Galen’s work to substantiate the view that the Prophet Muhammad ﷺ plagiarised from Greek writings on human development. However, upon analysing Galen’s writings, bringing it in contrast to the various and extensive meanings of the word mudghah, a pointed difference is made distinct. Galen states:

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. 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.69

As explored, the Qur’an mentions mudghah as a chewed-like substance and a small piece of flesh. In contrast, Galen discusses the “conformation” of “the three ruling parts”, “silhouettes” and “twigs”, which is most likely in reference to limb bone formation. He details these three ruling parts as being more visible than the stomach and the limbs. However, the Qur’an makes no mention of this, and its mention of the limb bone formation comes at the next stage. It is both implausible and impractical, therefore, to suggest the Prophet Muhammad ﷺ copied the works of Galen as the Qur’an does not include any of the descriptions provided by Galen at this stage
