Chapter: If one manumits a male slave owned by two persons
(4)
باب إِذَا أَعْتَقَ عَبْدًا بَيْنَ اثْنَيْنِ أَوْ أَمَةً بَيْنَ الشُّرَكَاءِ

Narrated `Abdullah bin `Umar:

Allah's Messenger (ﷺ) said, "Whoever frees his share of a common slave and he has sufficient money to free him completely, should let its price be estimated by a just man and give his partners the price of their shares and manumit the slave; otherwise (i.e. if he has not sufficient money) he manumits the slave partially."

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَنْ أَعْتَقَ شِرْكًا لَهُ فِي عَبْدٍ، فَكَانَ لَهُ مَالٌ يَبْلُغُ ثَمَنَ الْعَبْدِ قُوِّمَ الْعَبْدُ قِيمَةَ عَدْلٍ، فَأَعْطَى شُرَكَاءَهُ حِصَصَهُمْ وَعَتَقَ عَلَيْهِ، وَإِلاَّ فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ ‏"‏‏.‏
