Surah (:)
Sahih al-Bukhari
Forgetfulness in Prayer
Chapter: If one offers five Rak'a (instead of four)
Narrated' `Abdullah:
Once Allah's Messenger (ﷺ) offered five rak`at in the Zuhr prayer, and somebody asked him whether there was some increase in the prayer. Allah's Messenger (ﷺ) said, "What is that?" He said, "You have offered five rak`at." So Allah's Messenger (ﷺ) performed two prostrations of Sahu after Taslim.
