One night I slept at the house of (my aunt) Maimuna and the Prophet ﷺ was there on that night. He performed ablution and stood up for the prayer. I joined him and stood on his left side but he drew me to his right and prayed thirteen rakʿat and then slept till I heard his breath sounds. And whenever he slept, he used to breathe with audible sounds. The Mu'adh-dhin came to the Prophet ﷺ and he went out and prayed the morning prayer) without repeating the ablution.  

نِمْتُ عِنْدَ مَيْمُونَةَ وَالنَّبِيُّ ﷺ عِنْدَهَا تِلْكَ اللَّيْلَةَ فَتَوَضَّأَ ثُمَّ قَامَ يُصَلِّي فَقُمْتُ عَلَى يَسَارِهِ فَأَخَذَنِي فَجَعَلَنِي عَنْ يَمِينِهِ فَصَلَّى ثَلاَثَ عَشْرَةَ رَكْعَةً ثُمَّ نَامَ حَتَّى نَفَخَ وَكَانَ إِذَا نَامَ نَفَخَ ثُمَّ أَتَاهُ الْمُؤَذِّنُ فَخَرَجَ فَصَلَّى وَلَمْ يَتَوَضَّأْ قَالَ عَمْرٌو فَحَدَّثْتُ بِهِ بُكَيْرًا فَقَالَ حَدَّثَنِي كُرَيْبٌ بِذَلِكَ  

I slept (one night) in the house of Maimuna, the wife of the Messenger of Allah ﷺ, and the Messenger of Allah ﷺ was with her that night. He (after sleeping for half of the night got up and) then performed ablution and then stood up and observed prayer. I too stood on his left side. He took hold of me and made me stand on his right side. He (the Holy Prophet) observed thirteen rakʿahs on that night. The Messenger of Allah ﷺ then slept and snored and it was a habit with him to snore while sleeping. The Mu'adhdhin then came to him (to inform him about the prayer). He then went out and observed prayer without performing ablution. (ʿAmr said: Bukair b. Ashajj had narrated it to me ) (Using translation from Muslim 763d)  

أَنَّهُ قَالَ بِتُّ عِنْدَ خَالَتِي مَيْمُونَةَ وَرَسُولُ اللَّهِ ﷺ عِنْدَهَا تِلْكَ اللَّيْلَةَ «فَتَوَضَّأَ رَسُولُ اللَّهِ ﷺ ثُمَّ قَامَ يُصَلِّي فَقُمْتُ عَنْ يَسَارِهِ فَأَخَذَنِي فَجَعَلَنِي عَنْ يَمِينِهِ فَصَلَّى فِي تِلْكَ اللَّيْلَةِ ثَلَاثَ عَشْرَةَ رَكْعَةً ثُمَّ نَامَ رَسُولُ اللَّهِ ﷺ حَتَّى نَفَخَ وَكَانَ إِذَا نَامَ نَفَخَ ثُمَّ أَتَاهُ الْمُؤَذِّنُ فَخَرَجَ وَصَلَّى وَلَمْ يَتَوَضَّأْ» قَالَ عَمْرٌو حَدَّثْتُ بِهَذَا بُكَيْرَ بْنَ الْأَشَجِّ فَقَالَ حَدَّثَنِي كُرَيْبٌ بِذَلِكَ  

[Machine] I remained with Maymuna and the Messenger of Allah ﷺ was with her that night. The Messenger of Allah ﷺ performed ablution and stood up to pray, so I moved away from his left side. He took hold of me and placed me on his right side, and he prayed thirteen units of prayer that night. Then the Messenger of Allah ﷺ slept until he snored. When the Mu'adhdhin came to him, he got up and performed prayer without performing ablution.  

بِتُّ عِنْدَ مَيْمُونَةَ وَكَانَ رَسُولُ اللهِ ﷺ عِنْدَهَا تِلْكَ اللَّيْلَةَ «فَتَوَضَّأَ رَسُولُ اللهِ ﷺ وَقَامَ يُصَلِّي فَقُمْتُ عَنْ يَسَارِهِ فَأَخَذَنِي فَجَعَلَنِي عَنْ يَمِينِهِ فَصَلَّى تِلْكَ اللَّيْلَةَ ثَلَاثَ عَشْرَةَ رَكْعَةً ثُمَّ نَامَ رَسُولُ اللهِ ﷺ حَتَّى نَفَخَ وَكَانَ إِذَا نَامَ نَفَخَ ثُمَّ أَتَاهُ الْمُؤَذِّنُ فَخَرَجَ وَصَلَّى وَلَمْ يَتَوَضَّأْ»

بِتُّ عِنْدَ مَيْمُونَةَ زَوْجِ النَّبِيِّ ﷺ وَؓ وَرَسُولُ اللهِ ﷺ عِنْدَهَا تِلْكَ اللَّيْلَةَ فَتَوَضَّأَ رَسُولُ اللهِ ﷺ ثُمَّ قَامَ يُصَلِّي فَقُمْتُ عَنْ يَسَارِهِ فَأَخَذَنِي فَجَعَلَنِي عَنْ يَمِينِهِ فَصَلَّى فِي تِلْكَ اللَّيْلَةِ ثَلَاثَ عَشْرَةَ رَكْعَةً ثُمَّ نَامَ رَسُولُ اللهِ ﷺ حَتَّى نَفَخَ وَكَانَ إِذَا نَامَ نَفَخَ ثُمَّ أَتَاهُ الْمُؤَذِّنُ فَخَرَجَ فَصَلَّى وَلَمْ يَتَوَضَّأْ قَالَ عَمْرٌو فَحَدَّثْتُ بِهَا بُكَيْرَ بْنَ الْأَشَجِّ فَقَالَ حَدَّثَنِي كُرَيْبٌ بِذَلِكَ
