A'isha reported:The Messenger of Allah (ﷺ) used to observe thirteen rak'ahs of the night prayer. Five out of them consisted of Witr, and he did not sit, but at the end (for salutation)
Abu Salama b. Abd al-Rahman asked 'A'isha about the (night) prayer of the Messenger of Allah (ﷺ) during the month of Ramadan. She said:The Messenger of Allah (ﷺ) did not observe either in Ramadan or in other months more than eleven rak'ahs (of the night prayer). He (in the first instance) observed four rak'ahs. Ask not about their excellence and their length (i. e. these were matchless in perfection and length). He again observed four rak'ahs, and ask not about their excellence and their length. He would then observe three rak'ahs (of the Witr prayer). 'A'isha again said: I said: Messenger of Allah, do you sleep before observing the Witr prayer? He said: O 'A'isha, my eyes sleep but my heart does not sleep
Abu Salama asked 'A'isha about the prayer of the Messenger of Allah (ﷺ) She said:He observed thirteen rak'ahs (in the night prayer). He observed eight rak'ahs and would then observe Witr and then observe two rak'ahs sitting, and when he wanted to bow he stood up and then bowed down, and then observed two rak'ahs in between the Adhan and lqama of the dawn prayer
Abu Salama reported that he asked 'A'isha about the prayer of the Messenger of Allah (may peace he upon him) (during the night). The rest of the hadith is the same but with this exception that he (the Holy Prophet) observed nine rak'ahs including Witr
Abu Salama is reported to have said. I came to 'A'isha. I said:O mother, inform me about the prayer of the Messenger of Allah (ﷺ). She said: His (night prayer) in Ramadan and (during other months) was thirteen rak'ahs at night including two rak'ahs of fajr
حدیث 1727 — صحيح مسلم 6:156
حَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا حَنْظَلَةُ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، قَالَ سَمِعْتُ عَائِشَةَ، تَقُولُ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم مِنَ اللَّيْلِ عَشَرَ رَكَعَاتٍ وَيُوتِرُ بِسَجْدَةٍ وَيَرْكَعُ رَكْعَتَىِ الْفَجْرِ فَتِلْكَ ثَلاَثَ عَشْرَةَ رَكْعَةً .
It is reported on the authority of 'A'isha that the prayer of Allah's Messenger (ﷺ) in the night consisted of ten rak'ahs. He observed a Witr and two rak'ahs (of Sunan) of the dawn prayer, and thus the total comes to thirteen rak'ahs
A'isha thus reported about the (night prayer) of the Messenger of Allah (ﷺ):He used to sleep in the early part of the night, and woke up in the latter part. If he then wished intercourse with his wife, he satisfied his desire, and then went to sleep; and when the first call to prayer was made he jumped up (by Allah, she, i. e. 'A'isha, did not say" he stood up" ), and poured water over him (by Allah she, i. e. 'A'isha, did not say that he took a bath but I know what she meant) and if he did not have an intercourse, he performed ablution, just as a man performs ablution for prayer and then observed two rak'ahs
