[Machine] On the authority of the Prophet ﷺ who said, "If one of you feels drowsy while praying, let him sleep until his sleep is gone, for he may be seeking to ask for forgiveness and then end up cursing himself."  

عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا وَجَدَ أَحَدُكُمُ النَّوْمَ وَهُوَ يُصَلِّي فَلْيَنَمْ حَتَّى يَذْهَبَ نَوْمُهُ فَإِنَّهُ عَسَى يُرِيدُ أَنْ يَسْتَغْفِرَ فَيَسُبَّ نَفْسَهُ»
