Narrated Ibn 'Umar:
that 'Umar had vowed in the Pre-lslamic period to perform Itikaf in Al-Masjid-al-Haram. (A sub-narrator thinks that 'Umar vowed to perform Itikaf for one night.) Allah's Apostle ﷺ said to 'Umar, "Fulfill your vow."
حَدَّثَنَا عُبَيْدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ عُمَرَ ـ رضى الله عنه ـ نَذَرَ فِي الْجَاهِلِيَّةِ أَنْ يَعْتَكِفَ فِي الْمَسْجِدِ الْحَرَامِ ـ قَالَ أُرَاهُ قَالَ ـ لَيْلَةً قَالَ لَهُ رَسُولُ اللَّهِ ﷺ " أَوْفِ بِنَذْرِكَ ".
