ABUDAWUD 3947:
from Abīh Yablugh Bih —
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.
أبو داود ٣٩٤٧:
عن ابيه يبلغ به —
النَّبِيَّ ﷺ إِذَا كَانَ الْعَبْدُ بَيْنَ اثْنَيْنِ فَأَعْتَقَ أَحَدُهُمَا نَصِيبَهُ فَإِنْ كَانَ مُوسِرًا يُقَوَّمُ عَلَيْهِ قِيمَةً لاَ وَكْسَ وَلاَ شَطَطَ ثُمَّ يُعْتَقُ
