Sahih Muslim · Book 6: The Book of Prayer - Travellers · Night prayer, and the one who sleeps and misses it or is sick
وَحَدَّثَنَا عَلِيُّ بْنُ خَشْرَمٍ ، أَخْبَرَنَا عِيسَى، - وَهُوَ ابْنُ يُونُسَ - عَنْ شُعْبَةَ ، عَنْ قَتَادَةَ ، عَنْ زُرَارَةَ ، عَنْ سَعْدِ بْنِ هِشَامٍ الأَنْصَارِيِّ ، عَنْ عَائِشَةَ ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا عَمِلَ عَمَلاً أَثْبَتَهُ وَكَانَ إِذَا نَامَ مِنَ اللَّيْلِ أَوْ مَرِضَ صَلَّى مِنَ النَّهَارِ ثِنْتَىْ عَشْرَةَ رَكْعَةً . قَالَتْ وَمَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم قَامَ لَيْلَةً حَتَّى الصَّبَاحِ وَمَا صَامَ شَهْرًا مُتَتَابِعًا إِلاَّ رَمَضَانَ .
'A'isha reported that when the Messenger of Allah (ﷺ) decided upon doing any act, he continued to do it, and when he slept at night or fell sick he observed twelve rak'ahs during the daytime. I am not aware of Allah's Messenger (ﷺ) observing prayer during the whole of the night till morning, or observing fast for a whole month continuously except that of Ramadan.
