The Prophet ﷺ said: "If one of you is not sure about his prayer, let him forget about what he is unsure of and complete his prayer on the basis of what he is sure of. When he is sure that he has completed it, let him prostrate twice while he is sitting. Then if he has prayed five (rak'ahs), they (the two prostrations) will make his prayer even-numbered, and if he had prayed four, they will annoy and humiliate the shaitan."

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا شَكَّ أَحَدُكُمْ فِي صَلاَتِهِ فَلْيُلْغِ الشَّكَّ وَلْيَبْنِ عَلَى الْيَقِينِ فَإِذَا اسْتَيْقَنَ بِالتَّمَامِ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ قَاعِدٌ فَإِنْ كَانَ صَلَّى خَمْسًا شَفَعَتَا لَهُ صَلاَتَهُ وَإِنْ صَلَّى أَرْبَعًا كَانَتَا تَرْغِيمًا لِلشَّيْطَانِ

"The Messenger of Allah ﷺ said: 'If one of you is not sure about his prayer, let him estimate and prostrate twice after he has finished."

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا شَكَّ أَحَدُكُمْ فِي صَلاَتِهِ فَلْيَتَحَرَّ وَيَسْجُدْ سَجْدَتَيْنِ بَعْدَ مَا يَفْرُغُ

"Whoever has doubt, or is not sure, let him estimate what is correct, then let him prostrate twice."

مَنْ شَكَّ أَوْ أَوْهَمَ فَلْيَتَحَرَّ الصَّوَابَ ثُمَّ لْيَسْجُدْ سَجْدَتَيْنِ

“The Messenger of Allah ﷺ said: ‘If anyone of you is uncertain about his prayer, let him try to do what is correct then let him prostrate twice.’” Tanafisi said: "This is the basic rule, and no one is able to reject it."

رَسُولُ اللَّهِ ﷺ إِذَا شَكَّ أَحَدُكُمْ فِي الصَّلاَةِ فَلْيَتَحَرَّ الصَّوَابَ ثُمَّ يَسْجُدْ سَجْدَتَيْنِ قَالَ الطَّنَافِسِيُّ هَذَا الأَصْلُ وَلاَ يَقْدِرُ أَحَدٌ يَرُدُّهُ

[AI] The Messenger of Allah ﷺ said, "When one of you prays, let him cover himself for his prayer, even if it is with an arrow."

قَالَ رَسُولُ اللهِ ﷺ إِذَا صَلَّى أَحَدُكُمْ فَلْيَسْتَتِرْ لِصَلَاتِهِ وَلَوْ بِسَهْمٍ

[AI] "If one of you is unsure during his prayer, let him seek clarity within himself and complete it, then let him prostrate two prostrations after the salaam while sitting."

«إِذَا وَهِمَ أَحَدُكُمْ فِي صَلَاتِهِ فَلْيَتَحَرَّ الصَّوَابَ فِي نَفْسِهِ فَلْيُتِمَّ عَلَيْهِ ثُمَّ يَسْجُدْ سَجْدَتَيْنِ بَعْدَ التَّسْلِيمِ وَهُوَ جَالِسٌ»

[AI] The Prophet ﷺ said, "If any one of you has doubts about his prayer, he should follow what he thinks is correct and complete it, then make two prostrations."

[AI] On the authority of the Prophet, ﷺ , he said, "If anyone of you has doubt in his prayer, he should dispel the doubt and act upon certainty. Then, if he becomes certain, he should perform two prostrations while sitting."

عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا شَكَّ أَحَدُكُمْ فِي صَلَاتِهِ فَلْيُلْغِ الشَّكَّ وَلْيَبْنِ عَلَى الْيَقِينِ فَإِذَا اسْتَيْقَنَ بِالتَّمَامِ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ قَاعِدٌ»

"The Messenger of Allah ﷺ said: 'If one of you is not sure about his prayer, let him estimate and prostrate twice after he has finished." (Using translation from Nasāʾī 1241)

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