If anyone emancipates his share in a slave, he is to be completely emancipated by his money if he has money. But if he has no money, a fair price for the slave should be fixed, and the slave is required to work for his master according to the proportion of his price, but he must not be overburdened. Abu Dawud said: In the version of both the narrators the words are "he will be required to work and must not be overburdened". This is the version of 'Ali. (Using translation from Abū Dāʾūd 3938)   

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ أَعْتَقَ نَصِيبًا لَهُ فِي مَمْلُوكٍ فَخَلَاصُهُ عَلَيْهِ فِي مَالِهِ إِنْ كَانَ لَهُ مَالٌ فَإِنْ لَمْ يَكُنْ لَهُ مَالٌ قُوِّمَ ذَلِكَ الْعَبْدُ قِيمَةَ عَدْلِهِ وَاسْتَسْعَى فِي قِيمَتِهِ لِصَاحِبِهِ غَيْرَ مَشْقُوقٍ عَلَيْهِ»  

The Prophet ﷺ said, "Whoever manumits his share of a jointly possessed slave, it is imperative for him to get that slave manumitted completely by paying the remaining price, and if he does not have sufficient money to manumit him, then the price of the slave should be estimated justly, and he is to be allowed to work and earn the amount that will manumit him (without overburdening him)". (Using translation from Bukhārī 2492)   

أَنَّ النَّبِيَّ ﷺ قَالَ «مَنْ أَعْتَقَ شِقْصًا لَهُ فِي مَمْلُوكٍ فَعَلَيْهِ خَلَاصُهُ فِي مَالِهِ إِنْ كَانَ لَهُ مَالٌ وَإِلَّا قُوِّمَ الْمَمْلُوكُ قِيمَةَ عَدْلٍ فَاسْتَسْعَى غَيْرَ مَشْقُوقٍ عَلَيْهِ»  

If anyone emancipates a share in a slave, he is to be completely emancipated if he has money; but if he has none, the slave will be required to work to pay for his freedom, but must not be over-burhened. (Using translation from Muslim 1503a)  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ أَعْتَقَ شِقْصًا مِنْ عَبْدٍ فَخَلَاصُهُ مِنْ مَالِهِ إِنْ كَانَ لَهُ مَالٌ فَإِنْ لَمْ يَكُنْ لَهُ مَالٌ اسْتَسْعَى الْعَبْدُ غَيْرَ مَشْقُوقٍ عَلَيْهِ»  

If anyone emancipates a share in his slave, he should completely emancipate him if he has money; but if he has none, then slave will be required to work (to pay for his freedom), but he must not be overburdened. (Using translation from Abū Dāʾūd 3937)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنْ أَعْتَقَ شِقْصًا لَهُ مِنْ عَبْدٍ فَإِنَّ عَلَيْهِ أَنْ يُعْتِقَ بَقِيَّتَهُ إِنْ كَانَ لَهُ مَالٌ وَإِلَّا اسْتَسْعَى الْعَبْدُ غَيْرَ مَشْقُوقٍ عَلَيْهِ»  

The slave who is jointly owned by two persons, and is emancipated by one of them, (this one) has liability (upon him to secure complete freedom for that slave). (Using translation from Muslim 1502)   

عَنِ النَّبِيِّ ﷺ «فِي الْمَمْلُوكِ بَيْنَ الرَّجُلَيْنِ فَيُعْتِقُ أَحَدُهُمَا نَصِيبَهُ» قَالَ يَضْمَنُ  

[Machine] The Prophet ﷺ said, "Whoever sets free a share for himself from a slave, should set him free from his own wealth if he has it."  

أَنَّ النَّبِيَّ ﷺ قَالَ «مَنْ أَعْتَقَ نَصِيبًا لَهُ مِنْ مَمْلُوكٍ عَتَقَ مِنْ مَالِهِ إِنْ كَانَ لَهُ مَالٌ»  

[Machine] "Whoever frees a slave from his own wealth has indeed freed him if he possesses wealth."  

«مَنْ أَعْتَقَ شَقِيصًا مِنْ مَمْلُوكٍ عَتَقَ مِنْ مَالِهِ إِنْ كَانَ لَهُ مَالٌ»
