أَخْبَرَنَا عَمْرُو بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ عَبْدِ اللَّهِ بْنِ مُرَّةَ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ النَّذْرِ وَقَالَ " إِنَّهُ لاَ يَرُدُّ شَيْئًا إِنَّمَا يُسْتَخْرَجُ بِهِ مِنَ الشَّحِيحِ " .
