Sayyiduna Ali (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) once gifted me two slaves, and they were brothers. I sold one of them. One day, the Prophet (peace and blessings be upon him) asked me, "What happened to those slaves?" I replied that I had sold one of them. The Prophet (peace and blessings be upon him) said, "Take him back."
