The Book of Oaths
27/12. Chapter:
One who frees his share in a slave
Sahih Muslim
وَحَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " مَنْ أَعْتَقَ شِرْكًا لَهُ فِي عَبْدٍ عَتَقَ مَا بَقِيَ فِي مَالِهِ إِذَا كَانَ لَهُ مَالٌ يَبْلُغُ ثَمَنَ الْعَبْدِ " .
Ibn 'Umar reported Allah's Apostle (ﷺ) as saying: He who gives up his share in a slave, the remaining (share) will be paid out of his riches if his riches are enough to meet the price of the slave.
