وَإِنَّ لَكُمۡ فِي ٱلۡأَنۡعَٰمِ لَعِبۡرَةٗۖ نُّسۡقِيكُم مِّمَّا فِي بُطُونِهِۦ مِنۢ بَيۡنِ فَرۡثٖ وَدَمٖ لَّبَنًا خَالِصٗا سَآئِغٗا لِّلشَّٰرِبِينَ

Wa inna lakum fil an'aami la'ibrah; nusqeekum mimmmaa fee butoonihee mim baini farsinw wa damil labanann khaalisan saaa'ighallish shaaribeen

And verily in cattle (too) will ye find an instructive sign. From what is within their bodies between excretions and blood, We produce, for your drink, milk, pure and agreeable to those who drink it.

— Al-Nahl (ٱلنَّحْل), 16:66
