Lady Aisha (may Allah be pleased with her) narrates: The Noble Prophet (peace and blessings be upon him) sent Abu Sufyan to the city of Najran in Yemen, so that he may lead the prayers there, fight (in battle), and collect charity. The Noble Prophet (peace and blessings be upon him) also sent Rashid bin Abdullah with him. Whenever the Noble Prophet (peace and blessings be upon him) mentioned them, he would say: "Rashid is better than the entire tribe of Sulaym, and Abu Sufyan is better than the entire tribe of Uraynah." The Noble Prophet (peace and blessings be upon him) advised Abu Sufyan, instructing him to adopt the fear of Allah, and gave this guidance: "No person can divorce a woman whom he has not married, and no person can free a slave whom he does not own, and there is no validity to a vow made to disobey Allah."
