   And most surely there is a lesson for you in the cattle; We give you to drink of what is in their bellies-- from betwixt the feces and the blood-- pure milk, easy and agreeable to swallow for those who drink.
   

2. 47:15 مَّثَلُ ٱلْجَنَّةِ ٱلَّتِى وُعِدَ ٱلْمُتَّقُونَ فِيهَآ أَنْهَٰرٌ مِّن مَّآءٍ غَيْرِ ءَاسِنٍ وَأَنْهَٰرٌ مِّن لَّبَنٍ لَّمْ يَتَغَيَّرْ طَعْمُهُۥ وَأَنْهَٰرٌ مِّنْ خَمْرٍ لَّذَّةٍ لِّلشَّٰرِبِينَ وَأَنْهَٰرٌ مِّنْ عَسَلٍ مُّصَفًّى وَلَهُمْ فِيهَا مِن كُلِّ ٱلثَّمَرَٰتِ وَمَغْفِرَةٌ مِّن رَّبِّهِمْ كَمَنْ هُوَ خَٰلِدٌ فِى ٱلنَّارِ وَسُقُوا۟ مَآءً حَمِيمًا فَقَطَّعَ أَمْعَآءَهُمْ

   A parable of the garden which those guarding (against evil) are promised: Therein are rivers of water that does not alter, and rivers of milk the taste whereof does not change, and rivers of drink delicious to those who drink, and rivers of honey clarified and for them therein are all fruits and protection from their Lord. (Are these) like those who abide in the fire and who are made to drink boiling water so it rends their bowels asunder.
