حَدَّثَنَا وَكِيعٌ حَدَّثَنَا ابْنُ عَوْنٍ عَنْ زِيَادِ بْنِ جُبَيْرٍ أَنَّ رَجُلًا سَأَلَ ابْنَ عُمَرَ عَنْ رَجُلٍ نَذَرَ أَنْ يَصُومَ يَوْمًا فَوَافَقَ يَوْمَئِذٍ عِيدَ أَضْحَى أَوْ يَوْمَ فِطْرٍ فَقَالَ ابْنُ عُمَرَ أَمَرَ اللَّهُ بِوَفَاءِ النَّذْرِ وَنَهَانَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ صَوْمِ هَذَا الْيَوْمِ
