It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) say on the occasion of the Battle of Khaybar: "Tomorrow I will certainly give this banner to a man at whose hands Allah Almighty will grant victory." The people spent that night thinking it over, wondering to whom the banner would be given. When morning came, all the people came to the Messenger of Allah (peace and blessings be upon him), each of them hoping that the banner would be given to him. Then the Messenger of Allah (peace and blessings be upon him) asked: "Where is Ali bin Abi Talib?" The Companions said: "O Messenger of Allah, he has trouble with his eyes." He (peace and blessings be upon him) ordered that he be called, and when he was brought, he (peace and blessings be upon him) applied his blessed saliva to his eyes and supplicated for him, and he was cured at once, as if he had never had any trouble. Then he (peace and blessings be upon him) handed him the banner, and Sayyiduna Ali (may Allah be pleased with him) asked: "O Messenger of Allah, on what basis shall I fight these people?" He (peace and blessings be upon him) said: "Advance with complete calm and dignity until you descend upon their battlefield, then invite them to Allah, the Mighty and Majestic, and to His Messenger, until they become Muslims like us, and inform them of the rights of Allah that are binding upon them. For by Allah, if Allah Almighty guides even one man through you, that is far better for you than a fortune of precious red camels."
