حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ حَدَّثَنَا الْأَوْزَاعِيُّ عَنْ يَحْيَی بْنِ أَبِي کَثِيرٍ عَنْ أَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ النَّبِيُّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا نُودِيَ بِالصَّلَاةِ أَدْبَرَ الشَّيْطَانُ وَلَهُ ضُرَاطٌ فَإِذَا قُضِيَ أَقْبَلَ فَإِذَا ثُوِّبَ بِهَا أَدْبَرَ فَإِذَا قُضِيَ أَقْبَلَ حَتَّی يَخْطِرَ بَيْنَ الْإِنْسَانِ وَقَلْبِهِ فَيَقُولُ اذْکُرْ کَذَا وَکَذَا حَتَّی لَا يَدْرِيَ أَثَلَاثًا صَلَّی أَمْ أَرْبَعًا فَإِذَا لَمْ يَدْرِ ثَلَاثًا صَلَّی أَوْ أَرْبَعًا سَجَدَ سَجْدَتَيِ السَّهْوِ
صحیح بخاری · Hadith 3285
Narrated Abu Huraira: The Prophet said, "When the call for the prayer is pronounced, Satan takes to his heels, passing wind with noise, When the call for the prayer is finished, he comes back. And when the Iqama is pronounced, he again takes to his heels, and after its completion, he returns again to interfere between the (praying) person and his heart, saying to him. 'Remember this or that thing.' till the person forgets whether he has offered three or four rak`at: so if one forgets whether he has prayed three or four rak`at, he should perform two prostrations of Sahu (i.e. forgetfulness).
