He said: Suwayd b. `Abd al-`Aziz al-Dimishqi narrated to us from `Abdullah b. Lahi`a from Abi Qubayl from `Abdullah b. `Amr b. al-`As. He said:

On the day of Khaybar, the Messenger of Allah (s) gave the flag to a man from his companions. Then, he returned defeated. Then, he gave it to another, who behaved cowardly, and the flag returned defeated. So, the Messenger of Allah (s) said: Tomorrow, I will give the flag to a man who loves Allah and His Messenger, and Allah and His Messenger love him. He will not return until Allah conquers by his hand. When he awoke, he said: Call for `Ali for me. It was said to him: O Messenger of Allah! His eye in infected. So, he said: Call for him. When he came, the Messenger of Allah (s) spit in his eye and said: O Allah! Repel heat and cold from him. Then, he gave the flag to him and he went forth. He did not return to the Messenger of Allah (s) except that Khaybar was conquered. Then, he said: When he approached [Mount] Qamus, the enemies of Allah from the Jews came forth and shot arrows and stones at him. `Ali rode toward them until he approached the gate. Then, he disembarked angrily, went to the gate, and wrenched it off its hinges. Then, he threw it forty armlengths behind his back. Forty men tried to carry it, but hey could not handle it. So, the Prophet (s) was informed of that, and he said: By He in whose hand is my soul! Forty angels supported him in that.
