حَدَّثَنَا رَوْحٌ حَدَّثَنَا ابْنُ أَبِي حَفْصَةَ حَدَّثَنَا ابْنُ شِهَابٍ عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ عَنِ ابْنِ عَبَّاسٍ قَالَ اسْتَفْتَى سَعْدُ بْنُ عُبَادَةَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي نَذْرٍ عَلَى أُمِّهِ تُوُفِّيَتْ قَبْلَ أَنْ تَقْضِيَهُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اقْضِهِ عَنْهَا
