Sahih Muslim Book - 20, Hadith - 3774

وَحَدَّثَنَاهُ عَلِىُّ بْنُ خَشْرَمٍ أَخْبَرَنَا عِيسَى - يَعْنِى ابْنَ يُونُسَ - عَنْ سَعِيدِ بْنِ أَبِى عَرُوبَةَ بِهَذَا الإِسْنَادِ وَزَادَ « إِنْ لَمْ يَكُنْ لَهُ مَالٌ قُوِّمَ عَلَيْهِ الْعَبْدُ قِيمَةَ عَدْلٍ ثُمَّ يُسْتَسْعَى فِى نَصِيبِ الَّذِى لَمْ يُعْتِقْ غَيْرَ مَشْقُوقٍ عَلَيْهِ ».

It was narrated from Sa'eed bin Abi 'Arubah with this chain (a Hadith similar to no. 3773), and he added: "If he does not have any money, a fair price should be worked out for the slave, then let him work for the share that was not manumitted, without him being overburdened."
