Arabic (Original)
حَدَّثَنَا أَسْبَاطُ بْنُ مُحَمَّدٍ قَالَ حَدَّثَنَا مُطَرِّفٌ عَنْ أَبِي إِسْحَاقَ السُّبَيْعِيِّ عَنْ أَبِي عُبَيْدَةَ بْنِ عَبْدِ اللَّهِ قَالَ قُلْتُ لِعَائِشَةَ مَا الْكَوْثَرُ قَالَتْ نَهَرٌ أُعْطِيَهُ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي بُطْنَانِ الْجَنَّةِ قَالَ قُلْتُ وَمَا بُطْنَانُ الْجَنَّةِ قَالَتْ وَسَطُهَا حَافَّتَاهُ دُرَّةٌ مُجَوَّفٌ.
English Translation
Asbat ibn Muhammad told us: Mutarrif told us, from Abu Ishaq al-Sabi'i, from Abu Ubaydah ibn Abdullah, who said: I said to Aisha, "What is al-Kawthar?" She said: A river given to the Prophet, peace and blessings be upon him, in the innermost part of Paradise. He said: I said, "What is the innermost part of Paradise?" She said: Its middle; its two banks are of hollowed-out pearl.
