Sayyiduna al-Sa'ib (may Allah be pleased with him) relates: Sayyiduna Uthman bin Affan (may Allah be pleased with him) and Zuhayr bin Umayyah came and asked permission of the Prophet (peace and blessings be upon him) to enter, then the two of them praised me before him (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said: "I know him better than you two; he was my partner in the time of Jahiliyyah."
