Once I stayed overnight at the house of (my aunt ) Maimuna while the Prophet ﷺ was with her, to see how was the night prayer of Allah s Apostle Messenger of Allah ﷺ talked to his wife for a while and then slept. When it was the last third of the night (or part of it), the Prophet ﷺ got up and looked towards the sky and recited the Verse:-- 'Verily! In the creation of the Heavens and the Earth....there are indeed signs for the men of understanding.' (3.190) Then He got up and performed the ablution, brushed his teeth and offered eleven rakʿat. Then Bilal pronounced the Adhan whereupon the Prophet ﷺ offered a two-rakʿat (Sunna) prayer and went out to lead the people in Fajr (morning compulsory congregational prayer.  

بِتُّ فِي بَيْتِ مَيْمُونَةَ لَيْلَةً وَالنَّبِيُّ ﷺ عِنْدَهَا لأَنْظُرَ كَيْفَ صَلاَةُ رَسُولِ اللَّهِ ﷺ بِاللَّيْلِ فَتَحَدَّثَ رَسُولُ اللَّهِ ﷺ مَعَ أَهْلِهِ سَاعَةً ثُمَّ رَقَدَ فَلَمَّا كَانَ ثُلُثُ اللَّيْلِ الآخِرُ أَوْ بَعْضُهُ قَعَدَ فَنَظَرَ إِلَى السَّمَاءِ فَقَرَأَ {إِنَّ فِي خَلْقِ السَّمَوَاتِ وَالأَرْضِ} إِلَى قَوْلِهِ {لأُولِي الأَلْبَابِ} ثُمَّ قَامَ فَتَوَضَّأَ وَاسْتَنَّ ثُمَّ صَلَّى إِحْدَى عَشْرَةَ رَكْعَةً ثُمَّ أَذَّنَ بِلاَلٌ بِالصَّلاَةِ فَصَلَّى رَكْعَتَيْنِ ثُمَّ خَرَجَ فَصَلَّى لِلنَّاسِ الصُّبْحَ  

[Machine] I slept in the house of my aunt Maymuna, the wife of the Prophet ﷺ. The Prophet ﷺ was there. I observed how the Prophet ﷺ prayed at night. Then the Prophet ﷺ spoke to his family for a while and then went to sleep. When it was the last third or half of the night, he got up and looked at the sky and recited, "Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for those of understanding" until he finished reciting these verses. Then he got up, performed ablution, brushed his teeth, and prayed eleven units of prayer. Then Bilal called the prayer for Fajr and he prayed two units of prayer. Then he left and prayed in congregation with the people for Fajr.  

رَقَدْتُ فِي بَيْتِ خَالَتِي مَيْمُونَةَ زَوْجِ النَّبِيِّ ﷺ وَكَانَ النَّبِيُّ ﷺ عِنْدَهَا لَأَنْظُرَ كَيْفَ صَلَاةُ النَّبِيِّ ﷺ مِنَ اللَّيْلِ فَحَدَّثَ النَّبِيُّ ﷺ أَهْلَهُ سَاعَةً ثُمَّ رَقَدَ فَلَمَّا كَانَ ثُلُثُ اللَّيْلِ الْآخِرُ أَوْ نِصْفُهُ قَامَ فَنَظَرَ إِلَى السَّمَاءِ فَقَرَأَ {إِنَّ فِي خَلَقِ السَّماَوَاتِ وَالْأَرْضِ وَاخْتِلَافِ اللَّيْلِ وَالنَّهَارِ لَآيَاتٍ لِأُولِي الْأَلْبَابِ} حَتَّى قَرَأَ هَذِهِ الْآيَاتِ ثُمَّ قَامَ فَتَوَضَّأَ وَاسْتَنَّ ثُمَّ صَلَّى إِحْدَى عَشْرَةَ رَكْعَةً ثُمَّ أَذَّنَ بِلَالٌ بِالصَّلَاةِ فَصَلَّى رَكْعَتَيْنِ ثُمَّ خَرَجَ فَصَلَّى بِالنَّاسِ الصُّبْحَ
