Messenger of Allah, I had taken a vow during the days of Ignorance that I would observe I'tikaf for one day in the Sacred Mosque. So what is your opinion? He said: Go and observe I'tikaf for a day. And Messenger of Allah ﷺ gave him a slave girl out of the one-fifth (of the spoils of war meant for the Holy Prophet). And when Messenger of Allah (inay peace be upon him) set the war prisoners free. 'Umar b. Khattab heard their voice as they were saying: Messenger of Allah ﷺ has set as free. He (Hadrat 'Umar) said: What is this? They said: Messenger of Allah ﷺ has set free the prisoners of war (which had fallen to the lot of people). Thereupon he (Hadrat 'Umar) said: Abdullah, go to that slave-girl and set her free.  

أَنَّ عُمَرَ بْنَ الْخَطَّابِ سَأَلَ رَسُولَ اللَّهِ ﷺ وَهُوَ بِالْجِعْرَانَةِ بَعْدَ أَنْ رَجَعَ مِنَ الطَّائِفِ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي نَذَرْتُ فِي الْجَاهِلِيَّةِ أَنْ أَعْتَكِفَ يَوْمًا فِي الْمَسْجِدِ الْحَرَامِ فَكَيْفَ تَرَى قَالَ اذْهَبْ فَاعْتَكِفْ يَوْمًا قَالَ وَكَانَ رَسُولُ اللَّهِ ﷺ قَدْ أَعْطَاهُ جَارِيَةً مِنَ الْخُمْسِ فَلَمَّا أَعْتَقَ رَسُولُ اللَّهِ ﷺ سَبَايَا النَّاسِ سَمِعَ عُمَرُ بْنُ الْخَطَّابِ أَصْوَاتَهُمْ يَقُولُونَ أَعْتَقَنَا رَسُولُ اللَّهِ ﷺ فَقَالَ مَا هَذَا فَقَالُوا أَعْتَقَ رَسُولُ اللَّهِ ﷺ سَبَايَا النَّاسِ فَقَالَ عُمَرُ يَا عَبْدَ اللَّهِ اذْهَبْ إِلَى تِلْكَ الْجَارِيَةِ فَخَلِّ سَبِيلَهَا
