Sayyiduna Anas bin Malik (may Allah be pleased with him) said: Sayyiduna al-Bara' bin Malik (may Allah be pleased with him) lay down on his back, then began to hum (verses). So Anas (may Allah be pleased with him) said to him: "O my brother!" At that he sat upright and said: "O Anas, do you think I will die on my bed, when I have killed a hundred of the polytheists in single combat, besides those in whose killing I shared?"
