حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هُشَيْمٌ، حَدَّثَنَا أَبُو بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّهُ قَالَ فِي الْكَوْثَرِ هُوَ الْخَيْرُ الَّذِي أَعْطَاهُ اللَّهُ إِيَّاهُ. قَالَ أَبُو بِشْرٍ قُلْتُ لِسَعِيدِ بْنِ جُبَيْرٍ فَإِنَّ النَّاسَ يَزْعُمُونَ أَنَّهُ نَهَرٌ فِي الْجَنَّةِ. فَقَالَ سَعِيدٌ النَّهَرُ الَّذِي فِي الْجَنَّةِ مِنَ الْخَيْرِ الَّذِي أَعْطَاهُ اللَّهُ إِيَّاهُ.
