[Machine] From the Prophet, ﷺ , he said: Indeed, Satan comes to one of you during his prayer, and he does not know whether he has increased or decreased [his prayer]. So, when one of you finds that, let him perform two prostrations.  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الشَّيْطَانَ يَأْتِي أَحَدَكُمْ فِي صَلَاتِهِ فَلَا يَدْرِي أَزَادَ أَمْ نَقَصَ فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ  

Messenger of Allah (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." (Using translation from Tirmidhī 397)   

قَالَ رَسُولُ اللهِ ﷺ يَأْتِي أَحَدَكُمُ الشَّيْطَانُ فَيَلْبِسُ عَلَيْهِ فِي صَلَاتِهِ فَلَا يَدْرِي أَزَادَ أَمْ نَقَصَ فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

[Machine] Narrated Abu Sa'id and raised it to the Prophet ﷺ that he said, "If a man doubts in his prayer whether he has increased or decreased (the number of raka'at), he should perform two prostrations while sitting."  

عَنْ أَبِي سَعِيدٍ وَرَفَعَهُ إِلَى النَّبِيِّ ﷺ أَنَّهُ قَالَ إِذَا أَوْهَمَ الرَّجُلُ فِي صَلَاتِهِ فَلَمْ يَدْرِ أَزَادَ أَمْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

[Machine] On the authority of Abu Sa'id Al-Khudri, he reported from the Prophet ﷺ who said, "If a person becomes uncertain during their prayer as to whether they have added something or omitted something, then they should perform two prostrations (Sajdatayn) while still seated."  

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ يَرْفَعُهُ إِلَى النَّبِيِّ ﷺ قَالَ «إِذَا وَهِمَ الرَّجُلُ فِي صَلَاتِهِ فَلَمْ يَدْرِ أَزَادَ أَمْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ»  

[Machine] The Messenger of Allah ﷺ said, "If one of you prays and forgets or does not know if they have added or missed something, they should perform two prostrations while sitting."  

قَالَ رَسُولُ اللهِ ﷺ «إِذَا صَلَّى أَحَدُكُمْ فَنَسِيَ» أَوْ قَالَ «فَلَمْ يَدْرِ زَادَ أَوْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ»  

[Machine] The Messenger of Allah ﷺ said, "If one of you makes a mistake in his prayer and does not know whether he has added or missed something, he should perform two prostrations of forgetfulness while sitting." The rest of them disagreed with him.  

قَالَ رَسُولُ اللهِ ﷺ «إِذَا سَهَا أَحَدُكُمْ فِي صَلَاتِهِ فَلَا يَدْرِي زَادَ أَوْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ» خَالَفَهُ بَقِيَّةُ  

[Machine] The Messenger of Allah ﷺ said, "If anyone of you becomes uncertain during his prayer whether he has completed it or missed out something, he should perform two prostrations while sitting." Ikrimah bin Ammar contradicted them.  

قَالَ رَسُولُ اللهِ ﷺ «إِذَا سَهَا أَحَدُكُمْ فِي صَلَاتِهِ فَلَا يَدْرِي زَادَ أَوْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ» خَالَفَهُمْ عِكْرِمَةُ بْنُ عَمَّارٍ  

[Machine] The Messenger of Allah ﷺ said, "If one of you prays and does not know if he has added or subtracted, he should perform two prostrations while sitting and then say the salaam."  

قَالَ رَسُولُ اللهِ ﷺ «إِذَا صَلَّى أَحَدُكُمْ فَلَا يَدْرِي أَزَادَ أَوْ نَقَصَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ ثُمَّ يُسَلِّمُ»  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «إِذَا لَبَّسَ الشَّيْطَانُ عَلَى أَحَدِكُمْ فِي صَلَاتِهِ فَلَمْ يَدْرِ أَثَلَاثًا صَلَّى أَمْ أَرْبَعًا فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ»  

"إذَا صَلَّى أحدُكم فلمْ يدْرِ كيف صلَّى؟ فليسجدْ سجدَتين وَهُوَ جَالِسٌ".  

"إذا صلّى أحدُكُم فلم يدرِ أزادَ أمْ نقصَ؟ فليَسْجُدْ سجدَتَينْ وهو جالسٌ، ثُمَّ يسلِّم له".  

"يَأتِى الشَّيْطَانُ فَيَلْبسُ عَلَيْهِ فِى صَلَاتِهِ فَلَا يَدْرِى أَزَادَ أَمْ نَقَصَ، فَإِذَا وَجَدَ ذَلِكَ فَليَسْجُدْ سَجْدَتَيْن وَهُوَ جَالِسٌ".
