The stage of nash’ah |
The weight of the embryo increases noticeably. Voluntary and involuntary muscles develop, and voluntary movements start in this stage. In the 16th week (112 days) the foetus can grasp with his hands, kick, or even somersault (Figure 2). (Fig. 1) The 12th week ( around 84 days) the embryonic shape appears with sizes of head, body and limbs well formed, and fingers distinguished. Nash’ah: ‘formation of another creature’
In this stage the organs and the systems become well prepared to function. The foetus is ready for life outside the womb starting from the 22nd week to the 26th week (i.e., after the completion of the 6th month of gestation), when the respiratory system is ready to function and the nervous system is able to adjust the temperature of foetus body. In this stage, no new system or organs are formed, and the uterus provides food and suitable environment for the foetus to thrive until the stage of labour. Reflections on Quranic verses : This stage starts after the stage of clothing the bones with lahm (muscles and flesh), i.e., at the beginning of the 9th week, taking a period of almost 3 weeks. This is indicated with the use of conjunctive article (thumma) then, which denotes a time break between clothing with lahm and developing into another creature: He the Almighty says; “And clothed the bones with flesh; then We developed out of it another creature. So blessed be Allah, the best to create ” ( After the development of the cartilaginous skeleton, clothing it with muscles, and the head and the limbs are distinguished, the embryo changes into a human creature well differentiated from other creatures. During this stage, some important processes occur in the development of the embryo, which are clearly described in the Holy Quran and can be summarized as follows:
“He it is Who shapes you in the wombs as He pleases. There is no god but He, the Exalted in Might, the Wise.” (3:6) Here is an exquisite remark. Allah says in Surat Al Zumar; “He creates you in the wombs of your mothers in stages, one after another, in three veils of darkness.” (39:6), thus indicating the continuation of the embryonic development and the change from one stage into another, as explained earlier. Embryologists have confirmed that the foetus is surrounded, during the stages of development, with three membranes: 1- The amnion membrane which contains a fluid encompassing the foetus to make it in a state of swimming, thus protecting it from trauma that the uterus encounters, and facilitates the foetus movements for re-position smoothly during labour. (Figure 3) 2- The chorion membrane. 3- The decidua membrane. Some scholars interpreted the three veils of darkness with the amniotic membrane surrounding the uterus, wall of uterus, and abdomen wall (Figure 4). Yet, Allah knows best.
As we have mentioned before, the foetus becomes ready for life outside the womb after completion of the 6th month. It is noticed that the Quranic statement indicates in Surat Ahqaf that the stage of conception and incubation takes 30 months; “The bearing of him (the child) and the weaning of him is thirty months ” (Qur’an 46: 15), “And in two years was his weaning.” With a simple calculation, we deduce that the quranic statement decides that the least period of conception is 6 months as mentioned earlier, being a scientific fact, and before the 22nd week, in which this stage starts, the foetus is delivered abortus (not able to survive) in most cases. Praise be to Allah is the Omniscient. It is very interesting to mention that the first sense to develop in a developing human embryo is hearing. The foetus can hear sounds after the 24th week. Subsequently, the sense of sight is developed and by the 28th week, the retina becomes sensitive to light. Consider the following three Qur’anic verses related to the development of the senses in the embryo. And He gave you (the faculties of) hearing and sight and feeling (and understanding) Verily we created man from a drop of a mingled fluid-drop (nutfa amshaj), in order to try him: so we gave him (the gifts), of hearing and sight It is HE WHO has created for you (the faculties of) hearing, sight, feeling and understanding: little thanks it is ye give! In all these three verses, the sense of hearing is mentioned before the sense of sight. Thus the Qur’anic description matches with the discoveries in modern embroyolgy that the sense of hearing developes before the sense of sight. |
