مَّثَلُ ٱلْجَنَّةِ ٱلَّتِى وُعِدَ ٱلْمُتَّقُونَ ۖ فِيهَآ أَنْهَٰرٌۭ مِّن مَّآءٍ غَيْرِ ءَاسِنٍۢ وَأَنْهَٰرٌۭ مِّن لَّبَنٍۢ لَّمْ يَتَغَيَّرْ طَعْمُهُۥ وَأَنْهَٰرٌۭ مِّنْ خَمْرٍۢ لَّذَّةٍۢ لِّلشَّٰرِبِينَ وَأَنْهَٰرٌۭ مِّنْ عَسَلٍۢ مُّصَفًّۭى ۖ وَلَهُمْ فِيهَا مِن كُلِّ ٱلثَّمَرَٰتِ وَمَغْفِرَةٌۭ مِّن رَّبِّهِمْ ۖ كَمَنْ هُوَ خَٰلِدٌۭ فِى ٱلنَّارِ وَسُقُوا۟ مَآءً حَمِيمًۭا فَقَطَّعَ أَمْعَآءَهُمْ
A similitude of the Garden which those who keep their duty (to Allah) are promised: Therein are rivers of water unpolluted, and rivers of milk whereof the flavour changeth not, and rivers of wine delicious to the drinkers, and rivers of clear-run honey; therein for them is every kind of fruit, with pardon from their Lord. (Are those who enjoy all this) like those who are immortal in the Fire and are given boiling water to drink so that it teareth their bowels?
Surah Muhammad(47:15)
