Messenger of Allah ﷺ said, "When anyone of you stands for the prayers, Satan comes and puts him in doubts till he forgets how many rakʿat he has prayed. So if this happens to anyone of you, he should perform two prostrations of Sahu while sitting.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ حَتَّى لاَ يَدْرِيَ كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

The Messenger of Allah ﷺ said: When any one of you stands up to pray, the devil comes to him and confuses him to that he does not know how much he has prayed. If any one of you has such an experience he should perform two prostrations while sitting down (in qa'da).  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَهُ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

The Messenger of Allah ﷺ said: "When any one of you gets up and prays, the Shaitan comes to him an confuses him until he does not know how many (Rak'ahs) he prayed. If any one of you notices that, let him prostrate twice when he is sitting."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَهُ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ صَلاَتَهُ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

Abu Hurairah reported the Messenger of Allah ﷺ as saying; When one of you stands up to pray, the devil comes to him and confuses him so that he does not know how much he has prayed. If any of you has such an experience, he should perform two prostrations while he is sitting. Abu Dawud said; This tradition has been narrated in a similar manner by Ibn ‘Uyainab, Ma’mar and al-Laith.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَهُ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

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."  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الشَّيْطَانَ يَأْتِي أَحَدَكُمْ فِي صَلاَتِهِ فَيَلْبِسُ عَلَيْهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

Yahya related to me from Malik from Ibn Shihab from Abu Salama ibn Abdar-Rahman ibn Awf from Abu Hurayra that the Messenger of Allah ﷺ said, "When you stand in prayer, Shaytan comes to you and confuses you until you do not know how much you have prayed. If you find that happening do two sajdas from the sitting position."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي جَاءَهُ الشَّيْطَانُ فَلَبَسَ عَلَيْهِ حَتَّى لاَ يَدْرِي كَمْ صَلَّى فَإِذَا وَجَدَ ذَلِكَ أَحَدُكُمْ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ  

The Messenger of Allah ﷺ said: "When any one of you gets up and prays, the Shaitan comes to him an confuses him until he does not know how many (Rak'ahs) he prayed. If any one of you notices that, let him prostrate twice when he is sitting." (Using translation from Nasāʾī 1252)   

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «يَأْتِي الشَّيْطَانُ أَحَدَكُمْ وَهُوَ فِي صَلَاتِهِ لِيُلْبِسَ عَلَيْهِ حَتَّى لَا يَدْرِيَ كَمْ صَلَّى فَإِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ وَهُوَ جَالِسٌ»

Messenger of Allah ﷺ said, "When anyone of you stands for the prayers, Satan comes and puts him in doubts till he forgets how many rakʿat he has prayed. So if this happens to anyone of you, he should perform two prostrations of Sahu while sitting. (Using translation from Bukhārī 1232)   

"إِنَّ الشَّيطَانَ يَأْتِي أَحَدَكُمْ في صَلاته فَيُلْبِسُ عليه حَتَّى لا يَدْرى كَمْ صَلَّى. فَإِذَا وَجَدَ ذَلكَ أَحَدُكُمْ فَليَسْجُدْ سَجْدَتَينِ وَهُوَ جَالِسٌ قَبْلَ أن يُسَلَّمَ، ثُمَّ يُسَلِّمْ".  

"إِنَّ أحَدَكُمْ إِذا قام يُصَلِّى جاءَ الشيطان فَلَبَّسَ عليه حتى لا يدرى: كَمْ صَلَّى؟ فَإِذَا وَجَد ذلِك أحدُكم فَليَسْجُد سَجْدَتَيْن وهو جَالِسٌ".
