حَدَّثَنَا سُفْيَانُ بْنُ وَکِيعٍ حَدَّثَنَا يُونُسُ بْنُ بَکِيرٍ حَدَّثَنَا ابْنُ إِسْحَقَ أَخْبَرَنِي سَلَمَةُ بْنُ صَفْوَانَ بْنِ سَلَمَةَ عَنْ أَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ أَنَّ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ الشَّيْطَانَ يَدْخُلُ بَيْنَ ابْنِ آدَمَ وَبَيْنَ نَفْسِهِ فَلَا يَدْرِي کَمْ صَلَّی فَإِذَا وَجَدَ ذَلِکَ فَلْيَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ
ابن ماجہ · Hadith 1217
It was narrated from Abu Hurairah that the Prophet SAW said: "The Satan comes between the son of Adam and his soul, and he does not know how many Rak'ah he has prayed. If a person notices that, then let him prostrate twice before he says the Salam."(Hasan).
