عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَنْ أَعْتَقَ شِرْكًا لَهُ فِي عَبْدٍ فَكَانَ لَهُ مَا يَبْلُغُ ثَمَنَ الْعَبْدِ فَإِنَّهُ يُقَوَّمُ قِيمَةَ عَدْلٍ فَيُعْطَى شُرَكَاؤُهُ حَقَّهُمْ وَعَتَقَ عَلَيْهِ الْعَبْدُ وَإِلَّا فَقَدْ عَتَقَ مَا عَتَقَ
It is narrated from Sayyiduna Abdullah bin Umar, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Whoever frees his share in a slave, while he possesses wealth equal to the value of that slave, then the slave’s value will be assessed justly, and by paying the partners the value of their shares, the slave will be declared free. Otherwise, only the portion that the person has freed will be emancipated in that slave.
