حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ ‏:‏ ‏(‏ إناَّ، أَعْطَيْنَاكَ الْكَوْثَرَ ‏)‏ أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏"‏ هُوَ نَهْرٌ فِي الْجَنَّةِ ‏"‏ ‏.‏ قَالَ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ رَأَيْتُ نَهْرًا فِي الْجَنَّةِ حَافَتَاهُ قِبَابُ اللُّؤْلُؤِ قُلْتُ مَا هَذَا يَا جِبْرِيلُ قَالَ هَذَا الْكَوْثَرُ الَّذِي قَدْ أَعْطَاكَهُ اللَّهُ ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏

Anas narrated that the Messenger of Allah said

“While I was traveling through Paradise, a river appeared before me whose banks had tents of pearl. I said to the angel: ‘What is this?’ He said: ‘This is Al-Kauthar, which Allah has granted you.’” He said: “Then he put his hand in the clay, and removed musk from it, then I was raised up to Sidrat Al-Muntaha so I saw a magnificent light at it.”
