حَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا اللَّيْثُ عَنْ ابْنِ شِهَابٍ عَنْ أَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ الشَّيْطَانَ يَأْتِي أَحَدَکُمْ فِي صَلَاتِهِ فَيَلْبِسُ عَلَيْهِ حَتَّی لَا يَدْرِيَ کَمْ صَلَّی فَإِذَا وَجَدَ ذَلِکَ أَحَدُکُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ قَالَ أَبُو عِيسَی هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
جامع ترمذی · Hadith 397
Abu Hurairah narrated that: Allah's Messenger (S) said: Indeed the Shaitan comes to one of you in his Salat confusing him until he does now know how much he has prayed. When one of you experiences that then let him perform two prostrations while sitting.
