“One of us prays and he does not know how many (Rak’ah) he has prayed.” He said: “The Messenger of Allah ﷺ said: ‘When anyone of you prays and does not know how many he has prayed, let him perform two prostrations while he is sitting.’”  

أَحَدُنَا يُصَلِّي فَلاَ يَدْرِي كَمْ صَلَّى فَقَالَ قَالَ رَسُولُ اللَّهِ ﷺ إِذَا صَلَّى أَحَدُكُمْ فَلَمْ يَدْرِ كَمْ صَلَّى فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

[Machine] The Messenger of Allah ﷺ said, "If any one of you doubts his prayer, then he should strive to do what is right and perform two prostrations of forgetfulness while sitting."  

قَالَ رَسُولُ اللهِ ﷺ «إِذَا شَكَّ أَحَدُكُمْ فِي صَلَاتِهِ فَلْيَتَحَرَّ الصَّوَابَ وَلْيَسْجُدْ سَجْدَتَيِ السَّهْوِ 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 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»  

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

"إذا سَهَا أحدُكم في صلاتِه فلا يدْرى أزَادَ أمْ نقصَ؟ فليسْجدْ سجْدتين وهُوَ جَالِسٌ، ثُمَّ يُسَلِّم" .
