أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ عَبْدِ اللَّهِ بْنِ مُرَّةَ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " النَّذْرُ لاَ يُقَدِّمُ شَيْئًا وَلاَ يُؤَخِّرُهُ إِنَّمَا هُوَ شَىْءٌ يُسْتَخْرَجُ بِهِ مِنَ الشَّحِيحِ " .
