Iyas bin Salamah narrates from his father, Sayyiduna Salamah bin al-Akwa' (may Allah be pleased with him), that he said: We were present with the Messenger of Allah (peace and blessings be upon him) at the battle of Khaybar, when the Messenger of Allah (peace and blessings be upon him) put his saliva in the eyes of Sayyiduna Ali (may Allah be pleased with him) and he was cured. Then he (peace and blessings be upon him) gave him the banner. Then Marhab (the enemy's champion) came out reciting these verses: "Khaybar knows well that I am Marhab, armed to the teeth, a seasoned hero; when wars blaze up, I too become a flame." So Sayyiduna Ali (may Allah be pleased with him) came out against him saying: "I am the one whose mother named me Haydar (lion), like the lion of the forests, fearsome to behold; I will repay you with a great measure (sandarah) for a sa'." The narrator says: Then he struck Marhab such a blow that he split his head open and killed him, and thus victory was granted. This hadith is sahih (authentic) on the condition of Imam Muslim, but they did not record it with this wording.
