" 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.
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
" 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."
عَنِ ابْنِ أَبِي عَرُوبَةَ بِهَذَا الإِسْنَادِ وَفِي حَدِيثِ عِيسَى ثُمَّ يُسْتَسْعَى فِي نَصِيبِ الَّذِي لَمْ يُعْتِقْ غَيْرَ مَشْقُوقٍ عَلَيْهِ
“Whoever frees his share of a slave or part of his share, must pay from his wealth if he has any wealth if he has any wealth (in order to buy the rest of the slave's freedom). If he does not have wealth, then the slave should be asked to work for the price (of his freedom), without that causing him too much hardship.” (Using translation from Ibn Mājah 2527)
عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «مَنْ أَعْتَقَ شِقْصًا فِي مَمْلُوكٍ فَعَلَيْهِ خَلَاصُهُ فِي مَالِهِ إِنْ كَانَ لَهُ فَإِنْ لَمْ يَكُنْ لَهُ مَالٌ قُوِّمَ الْعَبْدُ قِيمَةَ عَدْلٍ ثُمَّ يُسْتَسْعَى فِي نَصِيبِ الَّذِي لَمْ يُعْتِقْ غَيْرَ مَشْقُوقٍ عَلَيْهِ»
