Sahih Muslim Book - 27, Hadith - 4294

وَحَدَّثَنِى أَبُو الطَّاهِرِ أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ أَنَّ أَيُّوبَ حَدَّثَهُ أَنَّ نَافِعًا حَدَّثَهُ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ حَدَّثَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ سَأَلَ رَسُولَ اللَّهِ -صلى الله عليه وسلم- وَهُوَ بِالْجِعْرَانَةِ بَعْدَ أَنْ رَجَعَ مِنَ الطَّائِفِ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّى نَذَرْتُ فِى الْجَاهِلِيَّةِ أَنْ أَعْتَكِفَ يَوْمًا فِى الْمَسْجِدِ الْحَرَامِ فَكَيْفَ تَرَى قَالَ « اذْهَبْ فَاعْتَكِفْ يَوْمًا ». قَالَ وَكَانَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- قَدْ أَعْطَاهُ جَارِيَةً مِنَ الْخُمْسِ فَلَمَّا أَعْتَقَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- سَبَايَا النَّاسِ سَمِعَ عُمَرُ بْنُ الْخَطَّابِ أَصْوَاتَهُمْ يَقُولُونَ أَعْتَقَنَا رَسُولُ اللَّهِ -صلى الله عليه وسلم-. فَقَالَ مَا هَذَا فَقَالُوا أَعْتَقَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- سَبَايَا النَّاسِ. فَقَالَ عُمَرُ يَا عَبْدَ اللَّهِ اذْهَبْ إِلَى تِلْكَ الْجَارِيَةِ فَخَلِّ سَبِيلَهَا.

'Abdullah bin 'Umar narrated that 'Umar bin Al-Khattab asked the Messenger of Allah (s.a.w) when he was in Al-Jir'anah, after he had come back from At-Ta'if: "O Messenger of Allah, during the Jahiliyyah I vowed that I would spend a day in I'tikaf in Al-Masjid Al-Haram. What do you think?" He said: "Go and spend a day in I'tikaf" He said: "And the Messenger of Allah (s.a.w) had given him a slave woman from the Khums, but when the Messenger of Allah (s.a.w) freed the captives, 'Umar bin Al-Khattab heard their voices saying: 'The Messenger of Allah (s.a.w) has set us free.' He said: 'What is this?' They said: 'The Messenger of Allah (s.a.w) has set the prisoners free.' 'Umar said: 'O 'Abdullah, go to that slave woman and set her free.'"
