Hadith 10:281
Abu Dharr reported God’s Messenger as saying, “Feed those of your slaves who please you from what you eat and clothe them from what you clothe yourselves, but sell those who do not please you and do not punish God’s creatures.” Ahmad and Abu Dawud transmitted it.
وَعَنْ أَبِي ذَرٍّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ لَاءَمَكُمْ مِنْ مَمْلُوكِيكُمْ فَأَطْعِمُوهُ مِمَّا تَأْكُلُونَ وَاكْسُوهُ مِمَّا تَكْسُونَ وَمَنْ لَا يُلَائِمُكُمْ مِنْهُمْ فَبِيعُوهُ وَلَا تُعَذِّبُوا خَلَقَ اللَّهِ» . رَوَاهُ أَحْمد وَأَبُو دَاوُد
