Not for you (O Muḥammad pbuh, but for Allah) is the decision.. (V.3:128)

That he heard Allah's Messenger (ﷺ) on raising his head from the bowing in the last rak`a in the Fajr prayer, saying, "O Allah, curse such-and-such person and such-and-such person, and such-and-such person," after saying, "Allah hears him who sends his praises to Him, O our Lord, all praise is for you." So Allah revealed:--"Not for you (O Muhammad) (but for Allah) is the decision, verily they are indeed wrongdoers." (3.128)

Save Al-Walid bin Al-Walid and Salama bin Hisham, and `Aiyash bin Abu Rabi`a. O Allah! Inflict Your Severe Torture on Mudar (tribe) and strike them with (famine) years like the years of Joseph." The Prophet (ﷺ) used to say in a loud voice, and he also used to say in some of his Fajr prayers, "O Allah! Curse soand- so and so-and-so." naming some of the Arab tribes till Allah revealed:--"Not for you (O Muhammad) (but for Allah) is the decision." (3.128)
