عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ فِي حَجَّةِ الْوَدَاعِ أَرِقَّاؤُكُمْ أَرِقَّاؤُكُمْ أَرِقَّاؤُكُمْ أَطْعِمُوهُمْ مِمَّا تَأْكُلُونَ وَاكْسُوهُمْ مِمَّا تَلْبَسُونَ فَإِنْ جَاءُوا بِذَنْبٍ لَا تُرِيدُونَ أَنْ تَغْفِرُوهُ فَبِيعُوا عِبَادَ اللَّهِ وَلَا تُعَذِّبُوهُمْ
It is narrated from Sayyiduna Yazid (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said at the occasion of the Farewell Pilgrimage: Take care of your slaves, take care of your slaves, take care of your slaves. Feed them from what you eat yourselves, and clothe them from what you wear yourselves. If they commit a sin which you do not wish to forgive, then sell these servants of Allah and do not punish them.
