And there is certainly a lesson for you in cattle: We give you to drink of what is in their bellies, from between digested food and blood: pure milk, pleasant to drink.1
— Dr. Mustafa Khattab, the Clear Quran
And indeed, for you in grazing livestock is a lesson. We give you drink from what is in their bellies - between excretion and blood - pure milk, palatable to drinkers.
