Narrated Salama: `Ali remained behind the Prophet during the Ghazwa of Khaibar as he was suffering from eye trouble. He then said, (How can) I remain behind the Prophet , and followed him. So when he slept on the night of the conquest of Khaibar, the Prophet said, I will give the flag tomorrow, or tomorrow the flag will be taken by a man who is loved by Allah and His Apostle , and (Khaibar) will be conquered through him, (with Allah's help) While every one of us was hopeful to have the flag, it was said, Here is `Ali and the Prophet gave him the flag and Khaibar was conquered through him (with Allah's Help).
