Arabic (Original)
حَدَّثَنَا يُونُسُ قَالَ حَدَّثَنَا حَمَّادٌ يَعْنِي ابْنَ سَلَمَةَ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ عَائِشَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا وَجَدَ أَحَدُكُمْ النَّوْمَ وَهُوَ يُصَلِّي فَلْيَرْقُدْ حَتَّى يَذْهَبَ نَوْمُهُ إِنَّ أَحَدَكُمْ عَسَى أَنْ يَذْهَبَ يَسْتَغْفِرُ اللَّهَ فَيَسُبُّ نَفْسَهُ.
English Translation
Yunus told us, Hammad -- that is Ibn Salama -- told us, from Hisham ibn Urwa, from his father, from Aisha, that the Messenger of Allah, peace and blessings be upon him, said: "If any of you feels drowsy while praying, let him sleep until his drowsiness passes, for one of you may go intending to ask Allah’s forgiveness and end up reviling himself."
