Salim b. ‘Umayr said – and he was one of the weepers of the Banu Najjar – ‘I vowed that I would kill Abu Afak or die in the attempt. I waited for a heedless moment.’ Then, one summer’s night, as Abu Afak slept in the courtyard with the Banu ‘Amr b. ‘Awf, Salim b. ‘Umayr approached, and pressed the sword upon his liver until it entered his bed. The enemy of God screamed. Those among the people who heard his words returned to him. They entered his place and buried him. They said, ‘Who killed him? By God, if we learn who killed him, we will surely kill him for it.’ Al-Nahdiyya, a Muslim woman, said these verses about that.
