The Book of Emancipating Slaves
Sahih Muslim #3647
كتاب العتق
وَحَدَّثَنَاهُ عَلِيُّ بْنُ خَشْرَمٍ، أَخْبَرَنَا عِيسَى، - يَعْنِي ابْنَ يُونُسَ - عَنْ سَعِيدِ بْنِ، أَبِي عَرُوبَةَ بِهَذَا الإِسْنَادِ وَزَادَ «إِنْ لَمْ يَكُنْ لَهُ مَالٌ قُوِّمَ عَلَيْهِ الْعَبْدُ قِيمَةَ عَدْلٍ ثُمَّ يُسْتَسْعَى فِي نَصِيبِ الَّذِي لَمْ يُعْتِقْ غَيْرَ مَشْقُوقٍ عَلَيْهِ».
This hadith has been narrated on the authority of Sa'id b. Abu 'Aruba with the same chain of transmitters but with the addition:
“If he (one of the joint owners emancipating the slave) has not (enough) money (to secure freedom for the other half) a fair price for the slave should be fixed, and he will be required to work to pay for his freedom, but must not be over-burdened.
