حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَبْدِ اللَّهِ، عَنْ أَخِيهِ، عَنْ سُلَيْمَانَ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنْ عُمَرَ بْنِ الْخَطَّابِ ـ رضى الله عنه ـ أَنَّهُ قَالَ يَا رَسُولَ اللَّهِ إِنِّي نَذَرْتُ فِي الْجَاهِلِيَّةِ أَنْ أَعْتَكِفَ لَيْلَةً فِي الْمَسْجِدِ الْحَرَامِ. فَقَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم " أَوْفِ نَذْرَكَ ". فَاعْتَكَفَ لَيْلَةً.
Ismail ibn Abd Allah narrated to us, from his brother, from Sulayman, from Ubayd Allah ibn Umar, from Nafi, from Abdullah ibn Umar, from Umar ibn al-Khattab, may Allah be pleased with him, who said: “O Messenger of Allah, in the pre-Islamic era I vowed to observe retreat for one night in the Sacred Mosque.” The Prophet, peace and blessings be upon him, said to him, “Fulfill your vow.” So he observed retreat for one night.
