Messenger of Allah 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." (Using translation from Bukhārī 2522)

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنْ أَعْتَقَ شِرْكًا لَهُ فِي عَبْدٍ فَكَانَ لَهُ مَالٌ يَبْلُغُ ثَمَنَ الْعَبْدِ قُوِّمَ عَلَيْهِ قِيمَةَ الْعَدْلِ وَأَعْطَى شُرَكَاءَهُ حِصَصَهُمْ وَأَعْتَقَ عَلَيْهِ الْعَبْدُ وَإِلَّا فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ»
