Sa'd ibn Ubadah
Late in 629 Abu Sufyan came to Medina seeking to renew the Treaty of Hudaybiya. When Muhammad's closest advisors had all refused to help him, he approached Sa'd ibn Ubadah, saying: "You know that I was your protector in Mecca and you were mine in Medina. You are the lord of this land. Grant protection among the people and increase the term [of the treaty]." Saad replied: "O Abu Sufyan, my protection is in the protection of God's Messenger. I will not grant protection against him."
