Surah 16. An-Nahl, Ayah 5

From wool, and hair, and skins, and milk. Camel's hair makes warm robes and blankets; and certain kinds of goats yield hair which makes similar fabrics. Sheep yield wool, and llamas alpaca for similar uses. The skins and furs of many animals yield warm raiment or make warm rugs or bedding. The females of many of these animals yield good warm milk, a nourishing and wholesome diet. Then the flesh of many of these animals is good to eat. There are other uses, which the animals serve, and which are referred to later.

Why will you go back to material things, considering that material things are made subservient to your use and enjoyment in various ways as suggested in the clauses that follow.
