Messenger of Allah ﷺ said, "If anyone of you feels drowsy while praying he should go to bed (sleep) till his slumber is over because in praying while drowsy one does not know whether one is asking for forgiveness or for a bad thing for oneself."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا نَعَسَ أَحَدُكُمْ وَهُوَ يُصَلِّي فَلْيَرْقُدْ حَتَّى يَذْهَبَ عَنْهُ النَّوْمُ فَإِنَّ أَحَدَكُمْ إِذَا صَلَّى وَهُوَ نَاعِسٌ لاَ يَدْرِي لَعَلَّهُ يَسْتَغْفِرُ فَيَسُبَّ نَفْسَهُ  

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  

When one of you dozes in prayer he should sleep till his sleep is gone, for when one of you prays while he is dozing, perhaps he might curse himself if he begs pardon of Allah.  

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

Messenger of Allah said: "When one of you is sleepy and he is performing Salat, then let him lie down until the sleep is gone from him. For when one of you performs Salat while he is sleepy, perhaps he wants to seek forgiveness but he curses himself."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا نَعَسَ أَحَدُكُمْ وَهُوَ يُصَلِّي فَلْيَرْقُدْ حَتَّى يَذْهَبَ عَنْهُ النَّوْمُ فَإِنَّ أَحَدَكُمْ إِذَا صَلَّى وَهُوَ يَنْعَسُ لَعَلَّهُ يَذْهَبُ يَسْتَغْفِرُ فَيَسُبَّ نَفْسَهُ قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ وَأَبِي هُرَيْرَةَ  

Yahya related to me from Malik from Hisham ibn Urwa from his father from A'isha, the wife of the Prophet ﷺ that the Messenger of Allah ﷺ said, "If you are drowsy in prayer, sleep until sleep leaves you, because if you pray while you are drowsy, you do not know whether you may intend to ask for forgiveness but (in fact) ask for harm."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا نَعَسَ أَحَدُكُمْ فِي صَلاَتِهِ فَلْيَرْقُدْ حَتَّى يَذْهَبَ عَنْهُ النَّوْمُ فَإِنَّ أَحَدَكُمْ إِذَا صَلَّى وَهُوَ نَاعِسٌ لاَ يَدْرِي 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  

When one of you dozes in prayer he should sleep till his sleep is gone, for when one of you prays while he is dozing, perhaps he might curse himself if he begs pardon of Allah. (Using translation from Abū Dāʾūd 1310)   

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا نَعَسَ أَحَدُكُمْ وَهُوَ يُصَلِّي 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 dozes off during his prayer, he should lie down, for perhaps he intends to seek forgiveness and consequently curse himself."  

قَالَ رَسُولُ اللهِ ﷺ إِذَا نَعَسَ أَحَدُكُمْ فِي صَلَاتِهِ فَلْيَنَمْ فَلَعَلَّهُ يُرِيدُ أَنْ يَسْتَغْفِرَ فَيَسُبَّ 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»  

When one of you dozes in prayer he should sleep till his sleep is gone, for when one of you prays while he is dozing, perhaps he might curse himself if he begs pardon of Allah. (Using translation from Abū Dāʾūd 1310)   

"إذَا نَعَسَ أحدُكُمْ في الصلاةِ فليرقد حتَّى يذهب عنه النومُ, فإِنَّ أحدَكُمْ إذَا صلَّى وهو ناعِسٌ لا يدْرى لعلَّه يذهبُ يستغفِرُ فيسُبُّ نفسَهُ".
