Prayer (Kitab Al-Salat)
2/204. Chapter:
Whoever Said The Doubt Should Be Ignored When One Is Confused Regarding (Whether He Has Prayed) Two Or Three Rak'ah
Sunan Abi Dawud
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الْعَزِيزِ بْنِ أَبِي رِزْمَةَ، أَخْبَرَنَا الْفَضْلُ بْنُ مُوسَى، عَنْ عَبْدِ اللَّهِ بْنِ كَيْسَانَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم سَمَّى سَجْدَتَىِ السَّهْوِ الْمُرْغِمَتَيْنِ .
Narrated Abdullah ibn Abbas: The Prophet (ﷺ) named the two prostrations of forgetfulness disgraceful for the devil.
