وَإِنَّ لَكُمْ فِى اْلاَنْعَامِ لَعِبْرَةً نُسْقِيكُمْ مِمَّا فِى بُطُونِهِ مِنْ بَيْنِ فَرْثٍ وَدَمٍ لَبَنًا خَالِصًا سَۤائِغًا لِلشَّارِبِينَ    

This verse (Nahl 16:66) is a decree overflowing with useful instruction. To place in the nipples of cows, camels, goats and sheep, as well as human mothers, in the midst of blood and excrement but without being polluted by them, a substance the exact opposite, pure, clean, pleasant, nutritive and white milk, and to inspire in their hearts tenderness toward their young that is still more pleasant, sweeter and more valuable than milk — this requires such a degree of mercy, wisdom, knowledge, power, will and care that it cannot in any way be the work of turbulent chance, of the tangled elements, or of blind forces.

The manifestation, workings and comprehensiveness of so miraculous a dominical art and so wise a Divine deed, all over the face of the globe and in the countless hearts and breasts of innumerable mothers of hundreds of thousands of species, in the same instant, the same fashion, with the same wisdom and the same care — this too constitutes a self-evident proof of Allah’s unity.
