How did the Messenger of Allah ﷺ pray during Ramadhan ? She said: The Messenger of Allah ﷺ did not pray more than eleven rak'ahs during Ramadhan and other than Ramadhan. He would pray four rak'ahs. Do not ask about their elegance and length. He then would pray for rak'ahs. Do not ask about their alegance and length. Then he would pray three rak'ahs. 'Aishah said: I asked: Messenger of Allah, do you sleep before observing witr ? He replied: 'Aishah, my eyes sleep, but my heart does not sleep. (Using translation from Abū Dāʾūd 1341)  

أَنَّهُ أَخْبَرَهُ أَنَّهُ سَأَلَ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ كَيْفَ كَانَتْ صَلَاةُ رَسُولِ اللهِ ﷺ فِي رَمَضَانَ؟ قَالَتْ مَا كَانَ يَزِيدُ فِي رَمَضَانَ وَلَا فِي غَيْرِهِ عَلَى إِحْدَى عَشْرَةَ رَكْعَةً يُصَلِّي أَرْبَعًا فَلَا تَسْأَلْ عَنْ حُسْنِهِنَّ وَطُولِهِنَّ ثُمَّ يُصَلِّي أَرْبَعًا فَلَا تَسْأَلْ عَنْ حُسْنِهِنَّ وَطُولِهِنَّ ثُمَّ يُصَلِّي ثَلَاثًا قَالَتْ عَائِشَةُ فَقُلْتُ يَا رَسُولَ اللهِ أَتَنَامُ قَبْلَ أَنْ تُوتِرَ قَالَ «يَا عَائِشَةُ إِنَّ عَيْنَيَّ تَنَامَانِ وَلَا يَنَامُ قَلْبِي» قَالَ أَبُو عَبْدِ الرَّحْمَنِ أَبُو سَعِيدٍ اسْمُهُ كَيْسَانَ

[Machine] The Messenger of Allah ﷺ used to pray thirteen rak'ahs at night, eight rak'ahs and then three rak'ahs of witr, and he would pray two rak'ahs for Fajr.  

كَانَ رَسُولُ اللهِ ﷺ «يُصَلِّي مِنَ اللَّيْلِ ثَلَاثَ عَشْرَةَ رَكْعَةً ثَمَانِ رَكَعَاتٍ وَيُوتِرُ بِثَلَاثٍ وَيَرْكَعُ رَكْعَتَيِ الْفَجْرِ»  

I would definitely watch at night the prayer observed by the Messenger of Allah ﷺ. He prayed two short rak'ahs, then two long, long, long rak'ahs, then he prayed two rak'ahs which were shorter than the two preceding rak'ahs, then he prayed two rak'ahs which were shorter than the two preceding, then he prayed two rak'ahs which were shorter than the two preceding, then observed a single one (Witr), making a total of thirteen rak'ahs (Using translation from Muslim 765)  

أَنَّهُ قَالَ لَأَرْمُقَنَّ صَلَاةَ رَسُولِ اللهِ ﷺ «فَصَلَّى رَكْعَتَيْنِ خَفِيفَتَيْنِ ثُمَّ صَلَّى رَكْعَتَيْنِ طَوِيلَتَيْنِ طَوِيلَتَيْنِ طَوِيلَتَيْنِ ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُمَا دُونَ اللَّتَيْنِ قَبْلَهُمَا ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُمَا دُونَ اللَّتَيْنِ قَبْلَهُمَا ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُمَا دُونَ اللَّتَيْنِ قَبْلَهُمَا ثُمَّ صَلَّى رَكْعَتَيْنِ وَهُمَا دُونَ اللَّتَيْنِ قَبْلَهُمَا»
