حَدَّثَنَا خَالِدُ بْنُ يَزِيدَ الْكَاهِلِيُّ، حَدَّثَنَا إِسْرَائِيلُ، عَنْ أَبِي إِسْحَاقَ، عَنْ أَبِي عُبَيْدَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَ سَأَلْتُهَا عَنْ قَوْلِهِ تَعَالَى ‏{‏إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ‏}‏ قَالَتْ نَهَرٌ أُعْطِيَهُ نَبِيُّكُمْ صلى الله عليه وسلم شَاطِئَاهُ عَلَيْهِ دُرٌّ مُجَوَّفٌ آنِيَتُهُ كَعَدَدِ النُّجُومِ‏.‏ رَوَاهُ زَكَرِيَّاءُ وَأَبُو الأَحْوَصِ وَمُطَرِّفٌ عَنْ أَبِي إِسْحَاقَ‏.‏
