Abu-Jahm bin Huzaifah narrates:

During the battle of Tarmuk, I went out in search of my cousin, who was in the forefront of the fight. I also took some water with me for him. I found him in the very thick of battle in the last moments of death. I advanced to help him with the little water that I had. But, soon, another sorely wounded soldier beside him gave a groan, and my cousin turned away his face, and asked me to take the water to that person first. I went to this other person with the water. He turned out to be Hisham bin Abilaas. But I had hardly reached him, when there was sound of another groan of yet another person lying not far off. Hisham too motioned me in his direction. Alas, before I could approach him, he had breathed his last. I made all haste back to Hisham and found him dead as well. Thereupon, I hurried as fast as I could to my cousin, and in the meantime he had also joined the other two. Innalillahi wa Inna ilaihi rejeun.
