Sahih Al Bukhari Hadith Number 797

Narrated Abu Salama: Abu Hurairah said, “No doubt, my Salat is similar to that of the Prophet (peace be upon him).” Abu Hurairah used to recite Qunut after saying Sami’ Allahu liman hamida in the last Rak’a of the Zuhr, Isha and Fajr Prayers. He would ask Allah’s Forgiveness for the true believers and curse the disbelievers.
