The Prophet (ﷺ) said, "Whoever frees a Muslim slave, Allah will save all the parts of his body from the (Hell) Fire as he has freed the body-parts of the slave." Sa`id bin Marjana said that he narrated that Hadith to `Ali bin Al-Husain and he freed his slave for whom `Abdullah bin Ja`far had offered him ten thousand Dirhams or one-thousand Dinars.
I asked the Prophet, "What is the best deed?" He replied, "To believe in Allah and to fight for His Cause." I then asked, "What is the best kind of manumission (of slaves)?" He replied, "The manumission of the most expensive slave and the most beloved by his master." I said, "If I cannot afford to do that?" He said, "Help the weak or do good for a person who cannot work for himself." I said, "If I cannot do that?" He said, "Refrain from harming others for this will be regarded as a charitable deed for your own good."
The Prophet (ﷺ) said, "Whoever manumits a slave owned by two masters, should manumit him completely (not partially) if he is rich after having its price evaluated."
Allah's Messenger (ﷺ) said, "Whoever frees his share of a common slave and he has sufficient money to free him completely, should let its price be estimated by a just man and give his partners the price of their shares and manumit the slave; otherwise (i.e. if he has not sufficient money) he manumits the slave partially."
Allah's Messenger (ﷺ) said, "Whoever manumits his share of a slave, then it is essential for him to get that slave manumitted' completely as long as he has the money to do so. If he has not sufficient money to pay the price of the other shares (after the price of the slave is evaluated justly), the manumitted manumits the slave partially in proportion to his share. `Ubaidullah narrated as above in brief.
The Prophet (ﷺ) said, "He who manumits his share of a slave and has money sufficient to free the remaining portion of that slave's price (justly estimated) then he should manumit him (by giving the rest of his price to the other co-owners)." Nafi` added, "Otherwise the slave is partially free." Aiyub is not sure whether the last statement was said by Nafi` or it was a part of the Hadith.
حَدَّثَنَا أَحْمَدُ بْنُ مِقْدَامٍ، حَدَّثَنَا الْفُضَيْلُ بْنُ سُلَيْمَانَ، حَدَّثَنَا مُوسَى بْنُ عُقْبَةَ، أَخْبَرَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّهُ كَانَ يُفْتِي فِي الْعَبْدِ أَوِ الأَمَةِ يَكُونُ بَيْنَ شُرَكَاءَ، فَيُعْتِقُ أَحَدُهُمْ نَصِيبَهُ مِنْهُ، يَقُولُ قَدْ وَجَبَ عَلَيْهِ عِتْقُهُ كُلِّهِ، إِذَا كَانَ لِلَّذِي أَعْتَقَ مِنَ الْمَالِ مَا يَبْلُغُ، يُقَوَّمُ مِنْ مَالِهِ قِيمَةَ الْعَدْلِ، وَيُدْفَعُ إِلَى الشُّرَكَاءِ أَنْصِبَاؤُهُمْ، وَيُخَلَّى سَبِيلُ الْمُعْتَقِ. يُخْبِرُ ذَلِكَ ابْنُ عُمَرَ عَنِ النَّبِيِّ صلى الله عليه وسلم. وَرَوَاهُ اللَّيْثُ وَابْنُ أَبِي ذِئْبٍ وَابْنُ إِسْحَاقَ وَجُوَيْرِيَةُ وَيَحْيَى بْنُ سَعِيدٍ وَإِسْمَاعِيلُ بْنُ أُمَيَّةَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم مُخْتَصَرًا.
That he used to give his verdict regarding the male or female slaves owned by more than one master, one of whom may manumit his share of the slave. Ibn `Umar used to say in such a case, "The manumitted should manumit the slave completely if he has sufficient money to pay the rest of the price of that slave (which is to be justly estimated) and the other shareholders are to take the price of their shares and the slave is freed (released from slavery)." Ibn `Umar narrated this verdict from the Prophet.
