Salim Ibn Umayr who was one of the great weepers and who had participated in Badr, said, "I take a vow that I shall either kill Abu Afak or die before him. He waited for an opportunity until a hot night came, and Abu Afak slept in an open place. Salim Ibn Umayr knew it, so he placed the sword on his liver and pressed it till it reached his bed. The enemy of Allah screamed and the people who were his followers, rushed to him, took him to his house and interred him."
