If anyone emancipates his share in slave, a fair price for the slave should be fixed, give his partners their shares, and the slave be thus emancipated. Otherwise he is emancipated to the extent of the share which he emancipated.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ أَعْتَقَ شِرْكًا لَهُ فِي مَمْلُوكٍ أُقِيمَ عَلَيْهِ قِيمَةَ الْعَدْلِ فَأَعْطَى شُرَكَاءَهُ حِصَصَهُمْ وَأُعْتِقَ عَلَيْهِ الْعَبْدُ وَإِلاَّ فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ  

He will be emancipated to the extent of the share which he emancipated, and sometimes he did not say these words.  

عَنِ النَّبِيِّ ﷺ بِمَعْنَاهُ قَالَ وَكَانَ نَافِعٌ رُبَّمَا قَالَ فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ وَرُبَّمَا لَمْ يَقُلْهُ  

I do not know whether the following words are part of the tradition of the Prophet ﷺ or Nafi' told them himself: "Otherwise he will be emancipated to the extent of the first man's share."  

عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ قَالَ أَيُّوبُ فَلاَ أَدْرِي هُوَ فِي الْحَدِيثِ عَنِ النَّبِيِّ ﷺ أَوْ شَىْءٌ قَالَهُ نَافِعٌ وَإِلاَّ عَتَقَ مِنْهُ مَا عَتَقَ  

If anyone emancipates his share in a slave, he should emancipate him completely if he has enough money to pay the full price ; but if he has none, he will be emancipated to the extent of his share.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَعْتَقَ شِرْكًا مِنْ مَمْلُوكٍ لَهُ فَعَلَيْهِ عِتْقُهُ كُلُّهُ إِنْ كَانَ لَهُ مَا يَبْلُغُ ثَمَنَهُ وَإِنْ لَمْ يَكُنْ لَهُ مَالٌ عَتَقَ نَصِيبُهُ  

The tradition mentioned above has also been transmitted by Ibn 'Umar from the Prophet ﷺ to the same effect as mentioned by Ibrahim b. Musa through a different chain.  

عَنِ النَّبِيِّ ﷺ بِمَعْنَى إِبْرَاهِيمَ بْنِ مُوسَى  

The tradition mentioned above has also been narrated by Ibn 'Umar through a different chain of transmitters to the same effect as mentioned by Malik. In this version there is no mention of the words "otherwise he will be emancipated to the extent of the first man's share." His version ends "and the slave be thus emancipated," to the same effect as he (Malik) mentioned.  

عَنِ النَّبِيِّ ﷺ بِمَعْنَى مَالِكٍ وَلَمْ يَذْكُرْ وَإِلاَّ فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ انْتَهَى حَدِيثُهُ إِلَى وَأُعْتِقَ عَلَيْهِ الْعَبْدُ عَلَى مَعْنَاهُ  

If a man emancipates his share in a slave, the rest will be emancipated by his money if he has enough money to pay the full price for him.  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ أَعْتَقَ شِرْكًا لَهُ فِي عَبْدٍ عَتَقَ مِنْهُ مَا بَقِيَ فِي مَالِهِ إِذَا كَانَ لَهُ مَا يَبْلُغُ ثَمَنَ الْعَبْدِ  

If a man is shared by two men, and one of them emancipates his share, a price of the slave will be fixed, not more or less, and he will be emancipated by him in case he is rich.  

النَّبِيَّ ﷺ إِذَا كَانَ الْعَبْدُ بَيْنَ اثْنَيْنِ فَأَعْتَقَ أَحَدُهُمَا نَصِيبَهُ فَإِنْ كَانَ مُوسِرًا يُقَوَّمُ عَلَيْهِ قِيمَةً لاَ وَكْسَ وَلاَ شَطَطَ ثُمَّ يُعْتَقُ  

On the authority of his father: A man emancipated his share in a slave. The Prophet ﷺ did not put the responsibility on him to emancipate the rest. Ahmad said: The name Ibn al-Thalabb is to be pronounced with a ta' (and not with tha). As Shu'bah could not pronounce ta, he said tha.  

أَنَّ رَجُلاً أَعْتَقَ نَصِيبًا لَهُ مِنْ مَمْلُوكٍ فَلَمْ يُضَمِّنْهُ النَّبِيُّ ﷺ قَالَ أَحْمَدُ إِنَّمَا هُوَ بِالتَّاءِ يَعْنِي التَّلِبَّ وَكَانَ شُعْبَةُ أَلْثَغَ لَمْ يُبَيِّنِ التَّاءَ مِنَ الثَّاءِ
