Anas narrated [regarding Allah, Most High’s saying] ‘Verily We have granted you Al-Kauthar’ (108:

1) that the Prophet ﷺ said: “It is a river in Paradise.” He said: “The Prophet ﷺ said: ‘I saw a river in Paradise, whose banks had tents were made of pearl. I said: “What is this O Jibril?’” He said: “This is Al-Kauthar which Allah has granted you.”

حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ : ( إناَّ، أَعْطَيْنَاكَ الْكَوْثَرَ ) أَنَّ النَّبِيَّ ﷺ قَالَ " هُوَ نَهْرٌ فِي الْجَنَّةِ " . قَالَ فَقَالَ النَّبِيُّ ﷺ " 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 .
