Quran 16:66 states: “And indeed, for you in livestock is a lesson. We give you drink from what is in their bellies—between excretion and blood—pure milk, palatable to drinkers.” This verse poetically references milk as a product from cattle but doesn’t scientifically explain its production. The biological process involves digestion, absorption, and hormonal regulation, none of which are detailed in the Quran. Instead, it reflects a general understanding of livestock as a resource.

Milk production in animals was well-known long before the Quran. Ancient civilizations, like the Sumerians, Greeks, and Romans, documented and used milk and dairy products. The practice of domesticating animals for milk dates back thousands of years. The Quran’s mention of milk production aligns with common knowledge of agrarian societies, not a unique scientific discovery.
