After Hamza b. ‘Abd al-Muttalib had been killed and mutilated and the Prophet s had seen him and said ‘Verily I will mutilate 70 of them for you’ the following was revealed And if you retaliate retaliate with the like of what you have been made to suffer; and yet if you endure patiently refraining from revenge verily that namely that enduring is better for the patient. Thus the Prophet s refrained from taking revenge and made atonement for his oath as reported by al-Bazzār.
