Sayyiduna Abdur Rahman bin Yazid narrates from his father that the Prophet (peace be upon him), while addressing during the Farewell Pilgrimage, said three times: Take care of your slaves; feed them what you eat, clothe them with what you wear. If they make a mistake which you cannot forgive, O servants of Allah, sell them, but do not punish them.
