Al-Mu'minun · 23:21

21. O people! Indeed, you have a lesson to take from grazing livestock (camels, cows and sheep), in that you can draw conclusions from them in the power of Allah and His kindness to you. He quenches your thirst with pure, tasty milk from the bellies of these animals. You can also derive other benefits from them, like conveyance, wool, fur, bristles, together with being able to consume their meat.
