Al-Aswad ibn Yazid said:

“I asked 'A'sha (may Allah be well pleased with her) about the nighttime ritual prayer of Allah’s Messenger (ﷺ), so she said: ‘He used to sleep at the beginning of the night. Then he would get up, and when it was the time before daybreak, he performed a witr [a ritual prayer with an odd number of cycles]. Then he came to his mattress, and if he had a need, he had sexual intercourse with his wife. When he heard the call to prayer, he sprang up, and if he was in a state of major ritual impurity, he poured water over himself, and if not, he performed the minor ritual ablution and went out to the ritual prayer.”

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ‏:‏ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، قَالَ‏:‏ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَسْوَدِ بْنِ يَزِيدَ، قَالَ‏:‏ سَأَلْتُ عَائِشَةَ، عَنْ صَلاةِ رَسُولِ اللهِ صلى الله عليه وسلم بِاللَّيْلِ‏؟‏ فَقَالَتْ‏:‏ كَانَ يَنَامُ أَوَّلَ اللَّيْلِ ثُمَّ يَقُومُ، فَإِذَا كَانَ مِنَ السَّحَرِ أَوْتَرَ، ثُمَّ أَتَى فِرَاشَهُ، فَإِذَا كَانَ لَهُ حَاجَةٌ أَلَمَّ بِأَهْلِهِ، فَإِذَا سَمِعَ الأَذَانَ وَثَبَ، فَإِنْ كَانَ جُنُبًا أَفَاضَ عَلَيْهِ مِنَ الْمَاءِ، وَإِلا تَوَضَّأَ وَخَرَجَ إِلَى الصَّلاةِ‏.‏
