Sayyiduna al-Sa'ib (may Allah be pleased with him) said: I came to the Messenger of Allah (peace and blessings be upon him), and the people began praising me and mentioning me. The Messenger of Allah (peace and blessings be upon him) said: "I know him better than all of you." Sayyiduna al-Sa'ib (may Allah be pleased with him) said: "You have spoken the truth, may my father and mother be sacrificed for you. You were my partner, and the best of partners; you neither disputed nor argued."
