Isḥāq b. Mūsá > Sufyān > Ayyūb > Nāfiʿ > Ibn ʿUmar > ʿUmar

It was narrated from ‘Umar that he had vowed during the days of Ignorance to spend one night in I’tikaf. He asked the Prophet ﷺ about it, so he commanded him to spend it in I’tikaf.

أَخْبَرَنَا إِسْحَاقُ بْنُ مُوسَى قَالَ حَدَّثَنَا سُفْيَانُ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنْ عُمَرَ

«أَنَّهُ كَانَ عَلَيْهِ لَيْلَةُ نَذْرٍ فِي الْجَاهِلِيَّةِ يَعْتَكِفُهَا فَسَأَلَ رَسُولَ اللهِ ﷺ فَأَمَرَهُ أَنْ يَعْتَكِفَ»
