At the mudghah stage, if an incision is made in the embryo and the internal organ is dissected, it will be seen that most of them are formed while the remaining are not yet completely formed.
According to Prof. Johnson, if we describe the embryo as a complete creation, then we are only describing that part which is already created. If we describe it as an incomplete creation, then we are only describing that part which is not yet created. So, is it a complete creation or an incomplete creation? There is no better description of this stage of embryogenesis than the Qur’anic description, “partly formed and partly unformed”, as in the following verse:
022.005► يَا أَيُّهَا النَّاسُ إِنْ كُنْتُمْ فِي رَيْبٍ مِنَ الْبَعْثِ فَإِنَّا خَلَقْنَاكُمْ مِنْ تُرَابٍ ثُمَّ مِنْ نُطْفَةٍ ثُمَّ مِنْ عَلَقَةٍ ثُمَّ مِنْ مُضْغَةٍ مُخَلَّقَةٍ وَغَيْرِ مُخَلَّقَةٍ لِنُبَيِّنَ لَكُمْ وَنُقِرُّ فِي الأرْحَامِ مَا نَشَاءُ إِلَى أَجَلٍ مُسَمًّى ثُمَّ نُخْرِجُكُمْ طِفْلا ثُمَّ لِتَبْلُغُوا أَشُدَّكُمْ وَمِنْكُمْ مَنْ يُتَوَفَّى وَمِنْكُمْ مَنْ يُرَدُّ إِلَى أَرْذَلِ الْعُمُرِ لِكَيْلا يَعْلَمَ مِنْ بَعْدِ عِلْمٍ شَيْئًا وَتَرَى الأرْضَ هَامِدَةً فَإِذَا أَنْزَلْنَا عَلَيْهَا الْمَاءَ اهْتَزَّتْ وَرَبَتْ وَأَنْبَتَتْ مِنْ كُلِّ زَوْجٍ بَهِيجٍ “We created you out of dust,then out of sperm,then out of a leech-like clot,then out of a morsel of flesh,partly formedand partly unformed that We may manifest (Our Power) to you.”[Al-Qur’an 22:5]
Scientifically we know that at this early stage of development there are some cells which are differentiated and there are some cells that are undifferentiated – some organs are formed and yet others unformed.
SENSE OF HEARING AND SIGHT
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.
The Qur’an explains it thus:
032.009► ثُمَّ سَوَّاهُ وَنَفَخَ فِيهِ مِنْ رُوحِهِ وَجَعَلَ لَكُمُ السَّمْعَ وَالأبْصَارَ وَالأفْئِدَةَ قَلِيلا مَا تَشْكُرُونَ “And He gave you (the faculties of) hearing and sight and feeling (and understanding).” [Al-Qur’an-Surah As-Sajda- 32:9]
“Verily We created man from a drop of mingled sperm, in order to try him: so We gave him (the gifts), of Hearing and Sight.” [Al-Qur’an 76:2]
“It is He Who has created for you (the faculties of) hearing, sight, feeling and understanding: little thanks it is ye give!”[Al-Qur’an 23:78]
In all these verses the sense of hearing is mentioned before that of sight. Thus the Qur’anic description matches perfectly with the discoveries in modern embryology.
