Musnad Ahmad

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that Marhab, the Jew, came out of his fortress, fully armed, and was reciting these lines of poetry: "All of Khaybar knows that I am Marhab, armed, brave, and experienced. Sometimes I fight with a spear and sometimes I strike with a sword. When lions advance like flames, it is as if my sanctuary is the true sanctuary, to which no one can come near." And he was shouting, "Is there anyone to face me?" The Prophet (peace and blessings be upon him) said: "Who will face him?" Sayyiduna Muhammad bin Maslamah stepped forward and said: "O Messenger of Allah! I will face him, and by Allah, I am his equal. He killed my brother yesterday." The Prophet (peace and blessings be upon him) said: "Go forward," and prayed, "O Allah, help him." When both came close to each other, a tree came between them, and one of them began to use it as a shield to avoid his opponent. Whenever he used it as a shield, the other would strike at him with his sword, until both came face to face and there was no barrier left between them. After that, Marhab attacked Muhammad bin Maslamah with his sword and struck him. He blocked it with his shield; the sword hit the shield and cut through it, but Muhammad bin Maslamah was saved. Then Muhammad bin Maslamah attacked him with his sword and did not stop until he killed him.
