He asked Aishah, the Mother of the Believers, about how the Messenger of Allah ﷺ used to pray in Ramadan. She said: "The Messenger of Allah ﷺ did not pray more than eleven rak'ahs during Ramadan or at any other time. He would pray four, and do not ask how beautiful or how long they were. Then he would pray four, and do not ask how beautiful or how long they were. Then he would pray three." Aishah said: "I said: 'O Messenger of Allah, do you sleep before you pray witr?' He said: 'O Aishah, my eyes sleep but my heart does not.'"  

أَنَّهُ أَخْبَرَهُ أَنَّهُ سَأَلَ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ كَيْفَ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ ﷺ فِي رَمَضَانَ قَالَتْ مَا كَانَ رَسُولُ اللَّهِ ﷺ يَزِيدُ فِي رَمَضَانَ وَلاَ غَيْرِهِ عَلَى إِحْدَى عَشْرَةَ رَكْعَةً يُصَلِّي أَرْبَعًا فَلاَ تَسْأَلْ عَنْ حُسْنِهِنَّ وَطُولِهِنَّ ثُمَّ يُصَلِّي أَرْبَعًا فَلاَ تَسْأَلْ عَنْ حُسْنِهِنَّ وَطُولِهِنَّ ثُمَّ يُصَلِّي ثَلاَثًا قَالَتْ عَائِشَةُ فَقُلْتُ يَا رَسُولَ اللَّهِ أَتَنَامُ قَبْلَ أَنْ تُوتِرَ قَالَ يَا عَائِشَةُ إِنَّ عَيْنِي تَنَامُ وَلاَ يَنَامُ قَلْبِي  

Aishah told him: "The Messenger of Allah ﷺ would not say the taslim for two rak'ahs during witr."  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ لاَ يُسَلِّمُ فِي رَكْعَتَىِ الْوَتْرِ
