أَخْبَرَنَا مُحَمَّدُ بْنُ صَدَقَةَ الْحِمْصِيُّ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ شُعَيْبٍ، عَنِ الأَوْزَاعِيِّ، عَنِ الزُّهْرِيِّ، أَخْبَرَهُ عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، عَنِ ابْنِ عَبَّاسٍ، عَنْ سَعْدِ بْنِ عُبَادَةَ، أَنَّهُ اسْتَفْتَى النَّبِيَّ صلى الله عليه وسلم فِي نَذْرٍ كَانَ عَلَى أُمِّهِ فَمَاتَتْ قَبْلَ أَنْ تَقْضِيَهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اقْضِهِ عَنْهَا ".
