Surah Al-Mu'minun 23:21
وَإِنَّ لَكُمْ فِى ٱلْأَنْعَـٰمِ لَعِبْرَةً ۖ نُّسْقِيكُم مِّمَّا فِى بُطُونِهَا وَلَكُمْ فِيهَا مَنَـٰفِعُ كَثِيرَةٌ وَمِنْهَا تَأْكُلُونَ
And indeed, for you in livestock is a lesson. We give you drink from that which is in their bellies, and for you in them are numerous benefits, and from them you eat.
