ʿUmar bin Al-Khattab said, "O Messenger of Allah ﷺ! I vowed to observe Iʿtikaf for one day during the Prelslamic period." The Prophet ﷺ ordered him to fulfill his vow. ʿUmar gained two lady captives from the war prisoners of Hunain and he left them in some of the houses at Mecca. When Messenger of Allah ﷺ freed the captives of Hunain without ransom, they came out walking in the streets. ʿUmar said (to his son), "O ʿAbdullah! See what is the matter." ʿAbdullah replied, "Messenger of Allah ﷺ has freed the captives without ransom." He said (to him), "Go and set free those two slave girls." (Nafiʿ added:) Allah's Apostle did not perform the ʿUmra from Al-Jarana, and if he had performed the ʿUmra, it would not have been hidden from ʿAbdullah.  

يَا رَسُولَ اللَّهِ إِنَّهُ كَانَ عَلَىَّ اعْتِكَافُ يَوْمٍ فِي الْجَاهِلِيَّةِ فَأَمَرَهُ أَنْ يَفِيَ بِهِ قَالَ وَأَصَابَ عُمَرُ جَارِيَتَيْنِ مِنْ سَبْىِ حُنَيْنٍ فَوَضَعَهُمَا فِي بَعْضِ بُيُوتِ مَكَّةَ قَالَ فَمَنَّ رَسُولُ اللَّهِ ﷺ عَلَى سَبْىِ حُنَيْنٍ فَجَعَلُوا يَسْعَوْنَ فِي السِّكَكِ فَقَالَ عُمَرُ يَا عَبْدَ اللَّهِ انْظُرْ مَا هَذَا فَقَالَ مَنَّ رَسُولُ اللَّهِ ﷺ عَلَى السَّبْىِ قَالَ اذْهَبْ فَأَرْسِلِ الْجَارِيَتَيْنِ قَالَ نَافِعٌ وَلَمْ يَعْتَمِرْ رَسُولُ اللَّهِ ﷺ مِنَ الْجِعْرَانَةِ وَلَوِ اعْتَمَرَ لَمْ يَخْفَ عَلَى عَبْدِ اللَّهِ وَزَادَ جَرِيرُ بْنُ حَازِمٍ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ مِنَ الْخُمُسِ وَرَوَاهُ مَعْمَرٌ عَنْ أَيُّوبَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ فِي النَّذْرِ وَلَمْ يَقُلْ يَوْمَ
