Arabic hadith text
أَخْبَرَنَا إِسْحَاقُ بْنُ مُوسَى، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنْ عُمَرَ، أَنَّهُ كَانَ عَلَيْهِ لَيْلَةٌ نَذَرَ فِي الْجَاهِلِيَّةِ يَعْتَكِفُهَا فَسَأَلَ رَسُولَ اللَّهِ صلى الله عليه وسلم فَأَمَرَهُ أَنْ يَعْتَكِفَ .
Translation
Ishaq ibn Musa reported to us; he said: Sufyan narrated to us, from Ayyub, from Nafiʿ, from Ibn ʿUmar, from ʿUmar, who had vowed during the pre-Islamic era to spend a night in devotional retreat. He asked the Messenger of Allah, peace and blessings be upon him, about it, and he instructed him to observe the retreat.
Translation notes
Iʿtikaf is devotional seclusion, usually observed in a mosque.
