On the day of Khaybar, Abu Bakr took the flag [in order to attempt the conquest of the fortress of Khaybar] but returned without having conquered it. Then the next day, 'Umar took it and did not conquer it, and instead Ibn Muslima was killed so the people retreated even further. So The Prophet (SAWA) said, 'I will deposit this flag of mine with a man who loves Allah and His Prophet, and whom Allah and His Prophet love, and he will not return without conquering it.' So we rested ourselves assured that the conquest would be tomorrow. So the Prophet (SAWA) performed the morning prayer then called for the flag, and stood up. And every single one of us who held a position with the Prophet (SAWA) hoped that it would be him, until I myself I stretched forward and craned my neck due to the The Battles position I had near him. Then he called 'Ali b. Abi Talib, who was afflicted with pain in his eyes. So the Prophet (SAWA) wiped his hands over them, deposited the flag with him, and he conquered it!'
