Sahih al-Bukhari, Hadith 2504 ⓘ

Narrated Abu Huraira: The Prophet said, "Whoever manumits his share of a jointly possessed slave, it is essential for him to manumit the slave completely if he has sufficient money. Otherwise he should look for some work for the slave (to earn what would enable him to emancipate himself), without overburdening him with work."

حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، عَنْ قَتَادَةَ، عَنِ النَّضْرِ بْنِ أَنَسٍ، عَنْ بَشِيرِ بْنِ نَهِيكٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ مَنْ أَعْتَقَ شِقْصًا لَهُ فِي عَبْدٍ، أُعْتِقَ كُلُّهُ إِنْ كَانَ لَهُ مَالٌ، وَإِلاَّ يُسْتَسْعَ غَيْرَ مَشْقُوقٍ عَلَيْهِ ‏" ‏‏.‏
