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  

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. (Using translation from Abū Dāʾūd 3947)  

النَّبِيَّ ﷺ إِذَا كَانَ الْعَبْدُ بَيْنَ اثْنَيْنِ فَأَعْتَقَ أَحَدُهُمَا نَصِيبَهُ فَإِنْ كَانَ مُوسِرًا قُوِّمَ عَلَيْهِ قِيمَةً لَا وَكْسَ وَلَا شَطَطَ ثُمَّ يُعْتَقُ  

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. (Using translation from Abū Dāʾūd 3947)  

أَنَّ النَّبِيَّ ﷺ قَالَ «إِذَا كَانَ عَبْدٌ بَيْنَ اثْنَيْنِ فَأَعْتَقَ أَحَدُهُمَا نَصِيبَهُ فَإِنْ كَانَ مُوسِرًا فَإِنَّهُ يُقَوَّمُ عَلَيْهِ قِيمَةٌ لَا وَكْسَ وَلَا شَطَطَ ثُمَّ يُعْتِقُ»  

He who emancipates a slave (shared) by him and another one, his full price may be justly assessed from his wealth, neither less nor more, and he (the slave) would be emancipated if he (the partner) would be solvent enough (to forgo the amount of his share). (Using translation from Muslim 1501g)   

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ أَعْتَقَ عَبْدًا بَيْنَهُ وَبَيْنَ آخَرَ قُوِّمَ عَلَيْهِ فِي مَالِهِ قِيمَةَ عَدْلٍ لَا وَكْسَ وَلَا شَطَطَ وَعَتَقَ عَلَيْهِ فِي مَالِهِ إِنْ كَانَ مُوسِرًا
