عَنْ سَالِمٍ عَنْ أَبِيهِ يَبْلُغُ بِهِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا كَانَ الْعَبْدُ بَيْنَ اثْنَيْنِ فَأَعْتَقَ أَحَدُهُمَا نَصِيبَهُ فَإِنْ كَانَ مُوسِرًا قُوِّمَ عَلَيْهِ قِيمَةٌ لَا وَكْسَ وَلَا شَطَطَ ثُمَّ يُعْتَقُ
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When two men own a slave in partnership and one of them frees his share, then if the one who freed is wealthy, the value of the slave will be assessed in such a way that neither less nor more is taken, and then the slave will be set free.
