AN NAHL — Ayat 66
وَإِنَّ لَكُمْ فِي الأَنْعَامِ لَعِبْرَةً نُّسْقِيكُم مِّمَّا فِي بُطُونِهِ مِن بَيْنِ فَرْثٍ وَدَمٍ لَّبَنًا خَالِصًا سَآئِغًا لِلشَّارِبِينَ
And indeed, for you in grazing livestock is a lesson. We give you drink from what is in their bellies - between excretion and blood - pure milk, palatable to drinkers.

وَإِنَّ لَكُمْ فِى الاٌّنْعَـمِ لَعِبْرَةً نُّسْقِيكُمْ مِّمَّا فِى بُطُونِهِ مِن بَيْنِ فَرْثٍ وَدَمٍ لَّبَنًا خَالِصًا سَآئِغًا لِلشَّارِبِينَ - وَمِن ثَمَرَتِ النَّخِيلِ وَالاٌّعْنَـبِ تَتَّخِذُونَ مِنْهُ سَكَرًا وَرِزْقًا حَسَنًا إِنَّ فِى ذلِكَ لآيَةً لِّقَوْمٍ يَعْقِلُونَ
66. And there is indeed a lesson for you in the An'am (cattle). We have made a drink for you out of what is in its belly, from between excretions and blood, pure milk; palatable to the drinkers. 67. And from the fruits of date palms and grapes, you derive strong drink and a goodly provision. There is indeed a sign in this for those of reason.
