Sahih Bukhari | Volume 5 | Hadith Number 397

That he heard Allah's Apostle, when raising his head from bowing of the first Rak'a of the morning prayer, saying, "O Allah! Curse so-and-so and so-and-so" after he had said, "Allah hears him who sends his praises to Him. Our Lord, all the Praises are for you!" So Allah revealed: "Not for you (O Muhammad!)... (till the end of Verse) they are indeed wrong-doers." (3:128) Salim bin 'Abdullah said' "Allah's Apostle used to invoke evil upon Safwan bin Umaiya, Suhail bin 'Amr and Al-Harith bin Hisham. So the Verse was revealed: "Not for you (O Muhammad!)... (till the end of Verse) For they are indeed wrong-doers." (3:128)
