Full Sharh — Sunan Ibn Majah 1217
حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، حَدَّثَنَا يُونُسُ بْنُ بُكَيْرٍ، حَدَّثَنَا ابْنُ إِسْحَاقَ، أَخْبَرَنِي سَلَمَةُ بْنُ صَفْوَانَ بْنِ سَلَمَةَ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَالَ " إِنَّ الشَّيْطَانَ يَدْخُلُ بَيْنَ ابْنِ آدَمَ وَبَيْنَ نَفْسِهِ فَلاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ قَبْلَ أَنْ يُسَلِّمَ " .
English Translation
It was narrated from Abu Hurairah that the Prophet (ﷺ) 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.”
