Forgetfulness in Prayer
كتاب السهو
Chapter 2: If one offers five Rak'a (instead of four)
باب إِذَا صَلَّى خَمْسًا
Sahih Al Bukhari 1226
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.
حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى الظُّهْرَ خَمْسًا فَقِيلَ لَهُ أَزِيدَ فِي الصَّلاَةِ فَقَالَ " وَمَا ذَاكَ ". قَالَ صَلَّيْتَ خَمْسًا. فَسَجَدَ سَجْدَتَيْنِ بَعْدَ مَا سَلَّمَ.
