Emancipation
Emancipating a Slave who is jointly owned, buying a relative, and emancipating during an illness - Section 1
وَعَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ أَعْتَقَ شِقْصًا فِي عَبْدٍ أُعْتِقَ كُلُّهُ إِنْ كَانَ لَهُ مَالٌ فَإِنْ لَمْ يَكُنْ لَهُ مَالٌ اسْتَسْعَى الْبعد غير مشقوق عَلَيْهِ»
Abu Huraira reported the Prophet (ﷺ) as saying, “If anyone emancipates a share in a slave, he is to be completely emancipated if he has money; but if he has none, the slave will be required to work to pay for his freedom, but must not be overburdened.” (Bukhari and Muslim.)
