When anyone amongst you dozes in prayer, he should sleep, till sleep is gone, for when one of you prays while dozing he does not know whether he may be asking pardon or vilifying himself.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا نَعَسَ أَحَدُكُمْ فِي الصَّلاَةِ فَلْيَرْقُدْ حَتَّى يَذْهَبَ عَنْهُ النَّوْمُ فَإِنَّ أَحَدَكُمْ إِذَا صَلَّى وَهُوَ نَاعِسٌ لَعَلَّهُ يَذْهَبُ يَسْتَغْفِرُ فَيَسُبُّ نَفْسَهُ  

"If anyone of you feels drowsy during his Salah, let him go and take a nap."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا نَعَسَ أَحَدُكُمْ فِي صَلاَتِهِ فَلْيَنْصَرِفْ وَلْيَرْقُدْ  

“The Prophet ﷺ said: ‘If anyone of you becomes drowsy, let him sleep until he feels refreshed, for he does not know, if he prays when he feels drowsy, he may want to say words seeking forgiveness but (instead) he ends up cursing himself.’”  

قَالَ النَّبِيُّ ﷺ إِذَا نَعَسَ أَحَدُكُمْ فَلْيَرْقُدْ حَتَّى يَذْهَبَ عَنْهُ النَّوْمُ فَإِنَّهُ لاَ يَدْرِي إِذَا صَلَّى وَهُوَ نَاعِسٌ لَعَلَّهُ يَذْهَبُ يَسْتَغْفِرُ فَيَسُبُّ نَفْسَهُ  

“The Prophet ﷺ said: ‘If anyone of you becomes drowsy, let him sleep until he feels refreshed, for he does not know, if he prays when he feels drowsy, he may want to say words seeking forgiveness but (instead) he ends up cursing himself.’” (Using translation from Ibn Mājah 1370)   

قَالَ رَسُولُ اللهِ ﷺ إِذَا نَعَسَ أَحَدُكُمْ فَلْيَرْقُدْ حَتَّى يَذْهَبَ عَنْهُ النَّوْمُ فَإِنَّهُ إِذَا صَلَّى وَهُوَ يَنْعَسُ لَعَلَّهُ يَذْهَبُ يَسْتَغْفِرُ فَيَسُبُّ نَفْسَهُ  

[Machine] The Messenger of Allah ﷺ said, "If one of you falls asleep while praying, let him lie down until sleep goes away. For if one of you stands up to pray while drowsy, he may pray seeking forgiveness and curse himself."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِذَا نَامَ أَحَدُكُمْ فِي صَلَاتِهِ فَلْيَرْقُدْ حَتَّى يَذْهَبَ عَنْهُ النَّوْمُ فَإِنَّ أَحَدَكُمْ إِذَا قَامَ يُصَلِّي وَهُوَ نَاعِسٌ لَعَلَّهُ يَسْتَغْفِرُ فَيَسُبُّ نَفْسَهُ»
