Compiled by Imam Muslim ibn al-Hajjaj
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قُلْتُ لِمَالِكٍ حَدَّثَكَ نَافِعٌ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أَعْتَقَ شِرْكًا لَهُ فِي عَبْدٍ فَكَانَ لَهُ مَالٌ يَبْلُغُ ثَمَنَ الْعَبْدِ قُوِّمَ عَلَيْهِ قِيمَةَ الْعَدْلِ فَأُعْطِيَ شُرَكَاؤُهُ حِصَصَهُمْ وَعَتَقَ عَلَيْهِ الْعَبْدُ وَإِلاَّ فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ" .
If anyone emancipates his share ina slave and has enough money to pay the full price for him, a fair price for the slave should be fixed, his partners given their shares, and the slave be thus emancipated, otherwise he is emancipated only to the extent of the first man's share.
