Hadith 5570
وَفِي أُخْرَى لَهُ عَنْ ثَوْبَانَ قَالَ: سُئِلَ عَنْ شَرَابِهِ. فَقَالَ: أَشَدُّ بَيَاضًا مِنَ اللَّبَنِ وَأَحْلَى مِنَ الْعَسَلِ يَغُتُّ فِيهِ مِيزَابَانِ يَمُدَّانِهِ مِنَ الْجَنَّةِ: أَحَدُهُمَا مِنْ ذَهَبٍ وَالْآخَرُ مِنْ ورق
In another version by him on Thauban's authority it is said that when he was asked about its drink he replied, "It is whiter than milk and sweeter than honey. Two pipes which supply it from paradise flow into it, one of gold and the other of silver." Muslim.
