Narrated Ibn `Umar: That he heard the Prophet, after raising his head from the bowing in morning prayer, saying, O Allah, our Lord! All the praises are for you. And in the last (rak`a) he said, O Allah! Curse so-and-so and so--and-so. And then Allah revealed:-- 'Not for you (O Muhammad) is the decision, (but for Allah), whether He turns in mercy to them or punish them, for they are indeed wrongdoers.' (3.128)
