" He will be required to work (in order to secure freedom) for that por- tion in which he has not been emancipated, without overburdening him."  

مسلم:١٥٠٣fوَحَدَّثَنَاهُ أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ وَمُحَمَّدُ بْنُ بِشْرٍ ح وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ وَعَلِيُّ بْنُ خَشْرَمٍ قَالاَ أَخْبَرَنَا عِيسَى بْنُ يُونُسَ جَمِيعًا

عَنِ ابْنِ أَبِي عَرُوبَةَ بِهَذَا الإِسْنَادِ وَفِي حَدِيثِ عِيسَى ثُمَّ يُسْتَسْعَى فِي نَصِيبِ الَّذِي لَمْ يُعْتِقْ غَيْرَ مَشْقُوقٍ عَلَيْهِ

" 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.  

مسلم:١٥٠٣bوَحَدَّثَنَاهُ 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
