حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، عَنْ عُمَرَ، رَضِيَ اللَّهُ عَنْهُ أَنَّهُ قَالَ ‏:‏ يَا رَسُولَ اللَّهِ إِنِّي نَذَرْتُ فِي الْجَاهِلِيَّةِ أَنْ أَعْتَكِفَ فِي الْمَسْجِدِ الْحَرَامِ لَيْلَةً ‏.‏ فَقَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم ‏:‏ ‏ "‏ أَوْفِ بِنَذْرِكَ ‏"‏ ‏.‏
