Prayer (Kitab Al-Salat)
2/202. Chapter:
(Prostrating For) Forgetfulness After The Two Prostrations (Rak'ah)
Sunan Abi Dawud
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ فَارِسٍ، حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، عَنِ الأَوْزَاعِيِّ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، وَأَبِي، سَلَمَةَ وَعُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ عَنْ أَبِي هُرَيْرَةَ، بِهَذِهِ الْقِصَّةِ قَالَ وَلَمْ يَسْجُدْ سَجْدَتَىِ السَّهْوِ حَتَّى يَقَّنَهُ اللَّهُ ذَلِكَ .
This tradition has also been transmitted by Abu Hurairah through a different chain of narrators. This version goes: he did not make two prostrations (at the end of prayer) due to forgetfulness until Allah gave him satisfaction about it.
