In the Holy Qur’án, when Alláh recounts His blessings to man, he mentions the cow:
Verily in cattle there is a lesson for you.
We give you to drink of what is inside their bodies, coming from between
the intestines and the blood, a milk pure and pleasant for those who drink it. (an-Nahl, 16:66)
The food that is eaten by the cow is digested in its intestines. From here the blood carries the nourishment to the rest of the body, including the mammary glands where the milk is produced.
Modern science tells us that the processes responsible for the production of milk begin when the contents of the intestine are brought together with the blood. And indeed, this is how the Holy Qur’án has explained it too.
We know that fruit is the end-product of the reproduction process of superior plants. The complex process starts at the flower, where the pollen carried by insects and birds causes fertilisation. Then the plant bears fruit, which in turn gives out seeds and the process begins all over again. All fruit, whether produced by cross or self-pollination requires the presence of male and female organs. The Holy Qur’án refers to this pair in several verses. One of them is:
You see the ground lifeless. When We send down water thereon, it stirs and grows and puts forth every magnificent pair (of plants) (al-Haj, 22:5)
Alláh has used this analogy to counter the arguments of the people who used to ask the Holy Prophet (S) how they would ever come back to life once they were dead. In several places in the Holy Qur’án, the reappearance of plant life in the spring is used as an example to explain the resurrection of humanity on the Day of Judgement.
The end of the reproductive process comes once the outer casing of the seed or fruit-stone is opened, allowing the fresh shoots to emerge and grow into a new plant. The Holy Qur’án refers to this process of germination:
Verily, Alláh splits the grain and the fruit-stone. (al-An`ám, 6:96)
Here again, Alláh mentions only in passing facts about His creation that science did not discover until centuries later!
