Messenger of Allah ﷺ said, "When the call for prayer is made, Satan takes to his heels passing wind so that he may not hear the Adhan and when the call is finished he comes back, and when the Iqama is pronounced, Satan again takes to his heels, and when the Iqama is finished he comes back again and tries to interfere with the person and his thoughts and say, "Remember this and that (which he has not thought of before the prayer)", till the praying person forgets how much he has prayed. If anyone of you does not remember whether he has offered three or four rakʿat then he should perform two prostrations of Sahu while sitting.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا نُودِيَ بِالصَّلاَةِ أَدْبَرَ الشَّيْطَانُ وَلَهُ ضُرَاطٌ حَتَّى لاَ يَسْمَعَ الأَذَانَ فَإِذَا قُضِيَ الأَذَانُ أَقْبَلَ فَإِذَا ثُوِّبَ بِهَا أَدْبَرَ فَإِذَا قُضِيَ التَّثْوِيبُ أَقْبَلَ حَتَّى يَخْطِرَ بَيْنَ الْمَرْءِ وَنَفْسِهِ يَقُولُ اذْكُرْ كَذَا وَكَذَا مَا لَمْ يَكُنْ يَذْكُرُ حَتَّى يَظَلَّ الرَّجُلُ إِنْ يَدْرِي كَمْ صَلَّى فَإِذَا لَمْ يَدْرِ أَحَدُكُمْ كَمْ صَلَّى ثَلاَثًا أَوْ أَرْبَعًا فَلْيَسْجُدْ سَجْدَتَيْنِ وَهْوَ جَالِسٌ  

The Messenger of Allah ﷺ said: When there is a call to prayer the devil runs back breaking the wind so that he may not hear the call, and when the call is complete he comes back. And when the takbir is pronounced he again runs back, and when takbir is over he comes back and distracts a man saying: Remember such and such, remember such and such, referring to something the man did not have in his mind. with the result that he does not know how much he has prayed; so when any one of you is not sure how much he has prayed. he should perform two prostrations while sitting (qa'da).  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا نُودِيَ بِالأَذَانِ أَدْبَرَ الشَّيْطَانُ لَهُ ضُرَاطٌ حَتَّى لاَ يَسْمَعَ الأَذَانَ فَإِذَا قُضِيَ الأَذَانُ أَقْبَلَ فَإِذَا ثُوِّبَ بِهَا أَدْبَرَ فَإِذَا قُضِيَ التَّثْوِيبُ أَقْبَلَ يَخْطُرُ بَيْنَ الْمَرْءِ وَنَفْسِهِ يَقُولُ اذْكُرْ كَذَا اذْكُرْ كَذَا لِمَا لَمْ يَكُنْ يَذْكُرُ حَتَّى يَظَلَّ الرَّجُلُ إِنْ يَدْرِي كَمْ صَلَّى فَإِذَا لَمْ يَدْرِ أَحَدُكُمْ كَمْ صَلَّى فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

"The Messenger of Allah ﷺ said: 'When the call to prayer is given, the Shaitan runs away breaking wind loudly. When the Tathwb (Iqamah) is completed, he comes back and whispers to a man in his hear, until he does not know how many (rak'ahs) he has prayed. If any one of you notices that, let him prostrate twice.'"  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا نُودِيَ لِلصَّلاَةِ أَدْبَرَ الشَّيْطَانُ لَهُ ضُرَاطٌ فَإِذَا قُضِيَ التَّثْوِيبُ أَقْبَلَ حَتَّى يَخْطُرَ بَيْنَ الْمَرْءِ وَقَلْبِهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا رَأَى أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا نُودِيَ لِلصَّلَاةِ أَدْبَرَ الشَّيْطَانُ وَلَهُ ضُرَاطٌ حَتَّى لَا يَسْمَعَ الْأَذَانَ فَإِذَا قُضِيَ الْأَذَانُ أَقْبَلَ فَإِذَا ثُوِّبَ بِهَا أَدْبَرَ فَإِذَا قُضِيَ التَّثْوِيبُ أَقْبَلَ يَخْطِرُ بَيْنَ الْمَرْءِ وَقَلْبِهِ أَوْ قَالَ نَفْسِهِ يَقُولُ اذْكُرْ كَذَا اذْكُرْ كَذَا لِمَا لَمْ يَكُنْ يَذْكُرُ حَتَّى يَظَلَّ الرَّجُلُ لَا يَدْرِي كَمْ صَلَّى فَإِذَا لَمْ يَدْرِ أَحَدُكُمْ كَمْصَلَّى ثَلَاثًا أَوْ أَرْبَعًا فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ

"إذا أذَّن المؤذِّن أدبر الشيطانُ وله ضراطٌ، فإذا سكت أقبل، فإذا ثوَّبَ أدبر وله ضراطٌ، فإذا سكت أقبل يخطُر بين المرءِ ونفسهِ حتى يظلَّ الرجلُ لا يدرى كم صلَّى، فإذا صلى أحدُكم فوجد ذلك فليسجد سجدتين وهو جالس".
