وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا، أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: إِذَا نَعَسَ أَحَدُكُمْ فِي الصَّلاَةِ، فَلْيَرْقُدْ حَتَّى يَذْهَبَ عَنْهُ النَّوْمُ، فَإِنَّ أَحَدَكُمْ إِذَا صَلَّى وَهُوَ نَاعِسٌ، لَعَلَّهُ يَذْهَبُ يَسْتَغْفِرُ فَيَسُبُّ نَفْسَهُ ((مُتَّفَقٌ عَلَيْهِ)).
'Aishah (May Allah be pleased with her) reported: The Prophet (ﷺ) said, "When one of you dozes off while performing Salat, he should lie down till his drowsiness has gone away from him. When one of you performs Salat while dozing, he may abuse himself instead of seeking pardon (as a result of drowsiness)." [Al-Bukhari and Muslim].
