وَإِنَّ لَكُمْ فِي الأَنْعَامِ لَعِبْرَةً نُّسْقِيكُم مِّمَّا فِي بُطُونِهِ مِن بَيْنِ فَرْثٍ وَدَمٍ لَّبَنًا خَالِصًا سَآئِغًا لِلشَّارِبِينَ
﴿٦٦﴾
سورة النحل
(16/66) And verily there is for you in the cattle a lesson: We give you to drink of that which is in their bellies, from betwixt the dung and the blood: milk Pure and pleasant to swallow for the drinkers.
