(Al-Muaminoon) 23 : 21
وَإِنَّ لَكُمْ فِي الْأَنْعَامِ لَعِبْرَةً ۖ نُسْقِيكُمْ مِمَّا فِي بُطُونِهَا وَلَكُمْ فِيهَا مَنَافِعُ كَثِيرَةٌ وَمِنْهَا تَأْكُلُونَ
And indeed, you have a moral in livestock. We give you a drink from that which is in their bellies, and for you in them are numerous benefits, and you are eating from them.
