حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ عُمَرَ بْنِ الْخَطَّابِ، قَالَ نَذَرْتُ نَذْرًا فِي الْجَاهِلِيَّةِ فَسَأَلْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ بَعْدَ مَا أَسْلَمْتُ فَأَمَرَنِي أَنْ أُوفِيَ بِنَذْرِي ‏.‏
