Blood circulation & milkThe Qur’an was revealed 600 years before the Muslim scientist Ibn Nafees described the circulation of the blood and 1,000 years before William Harwey brought this understanding to the Western world. Roughly thirteen centuries before it was known what happens in the intestines to ensure that organs are nourished by the process of digestive absorption, a verse in the Qur’an described the source of the constituents of milk, in conformity with these notions.
To understand the Qur’anic verse concerning the above concepts, it is important to know that chemical reactions occur in the
intestines and that, from there, substances extracted from food pass into the blood stream via a complex system; sometimes by way of the liver, depending on their chemical nature. The blood transports them to all the organs of the body, among which are the milk-producing mammary glands.
In simple terms, certain substances

16:66 ►“ وَإِنَّ لَكُمْ فِي الأنْعَامِ لَعِبْرَةً نُسْقِيكُمْ مِمَّا فِي بُطُونِهِ مِنْ بَيْنِ فَرْثٍ وَدَمٍ لَبَنًا خَالِصًا سَائِغًا لِلشَّارِبِينَ “
“And verily in cattle there is a lesson for you. We give you to drink coming from a conjunction between the contents of the intestine and the blood, a milk pure and pleasant for those who drink it.” [Al-Qur’an- Surah Nahal 16:66]
Another verse also touches on concerning issue:
23:21 ►“ وَإِنَّ لَكُمْ فِي الأنْعَامِ لَعِبْرَةً نُسْقِيكُمْ مِمَّا فِي بُطُونِهَا وَلَكُمْ فِيهَا مَنَافِعُ كَثِيرَةٌ وَمِنْهَا تَأْكُلُونَ “
“And in cattle (too) ye from within their bodies We produce (milk) for you to drink; there are, in them, (besides), numerous (other) benefits for you; and of their (meat) ye eat.” [Al-Qur’an-Surah Al-Mumenoon- 23:21]
