The apostle said, 'Who will deal with this fellow?' Muhammad bin Maslama said that he would, for he was bound to take revenge on the man who had killed his brother the day before. The apostle told him to go and prayed Allah to help him. When they approached the one the other an old tree with soft wood lay between them and they began to hide behind it. Each took shelter from the other. When one hid behind the tree the other slashed at it with his sword so that the intervening branches were cut away and they came face to face. The tree remained bereft of its branches like a man standing upright. Then Marhab attacked Muhammad b. Maslama and struck him. He took the blow on his shield and the sword bit into it and remained fast. Muhammad (bin Maslama) then gave Marhab a fatal wound.”
