Wrapping Muscles over Bones

Another important item of information provided in the verses of the Qur’an is the developmental stages of a human being in the mother’s womb. It is stated in these verses that in the mother’s womb, the bones develop first, and then the muscles form which wrap around them.

023.014► ثُمَّ خَلَقْنَا النُّطْفَةَ عَلَقَةً فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنْشَأْنَاهُ خَلْقًا آخَرَ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ


[We] then formed the drop into an embryo and formed the embryo into a lump and formed the lump into bones and clothed the bones in flesh; and then brought him into being as another creature. Blessed be Allah, the Best of Creators! (Qur’an, Al-Mumenoon -23:14)


 Embryology is the branch of science that studies the development of the embryo in the mother’s womb. Until very recently, embryologists assumed that the bones and muscles in an embryo developed at the same time. Yet, advanced microscopic research conducted by virtue of new technological developments has revealed that the revelation of the Qur’an is word for word correct.

These observations at the microscopic level showed that the development inside the mother’s womb takes place in just the way it is described in these verses. First, the cartilage tissue of the embryo ossifies. Then, muscular cells that are selected from amongst the tissue around the bones come together and wrap around the bones.
This event is described in a scientific publication titled Developing Human in the following words:
… [T]he shape of the skeleton determines the general appearance of the embryo in the bones stage during the 7th week; muscles do not develop at the same time but their development follows soon after. The muscles take their positions around the bones throughout the body and therefore clothe the bones. Thus, the muscles take their well known forms and structures… The stage of clothing with muscle occurs during the 8th week…90
In short, developmental stages of man, as described in the Qur’an, are in perfect harmony with the findings of modern embryology.
