أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا يَحْيَى بْنُ آدَمَ، قَالَ حَدَّثَنَا شَرِيكٌ، عَنْ أَبِي إِسْحَاقَ، عَنْ يَحْيَى بْنِ عُبَيْدٍ الْبَهْرَانِيِّ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُنْقَعُ لَهُ الزَّبِيبُ فَيَشْرَبُهُ يَوْمَهُ وَالْغَدَ وَبَعْدَ الْغَدِ .
