Sa'eed bin Abi Sa'eed Al-Maqburi narrated that Abu Salamah informed him that he had asked Aishah: "How was the Salat of Allah's Messenger ﷺ [at night] during Ramadan?" She said: "Allah's Messenger ﷺ would pray - neither in Ramadan nor in any other month - more than eleven Rak'ah. He would pray four, and do not ask about their excellence or length, then he would pray four, and do not ask about their excellence or length, then he would pray three." Aishah said: "I asked: 'O Messenger of Allah! Do you sleep before having performed Witr?" He said: 'O Aishah! Indeed my eyes sleep but my heart does not sleep.'"

حَدَّثَنَا إِسْحَاقُ بْنُ مُوسَى الأَنْصَارِيُّ، حَدَّثَنَا مَعْنٌ، حَدَّثَنَا مَالِكٌ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي سَلَمَةَ، أَنَّهُ أَخْبَرَهُ أَنَّهُ، سَأَلَ عَائِشَةَ كَيْفَ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ ﷺ بِاللَّيْلِ فِي رَمَضَانَ فَقَالَتْ مَا كَانَ رَسُولُ اللَّهِ ﷺ يَزِيدُ فِي رَمَضَانَ وَلاَ فِي غَيْرِهِ عَلَى إِحْدَى عَشْرَةَ رَكْعَةً يُصَلِّي أَرْبَعًا فَلاَ تَسْأَلْ عَنْ حُسْنِهِنَّ وَطُولِهِنَّ ثُمَّ يُصَلِّي أَرْبَعًا فَلاَ تَسْأَلْ عَنْ حُسْنِهِنَّ وَطُولِهِنَّ ثُمَّ يُصَلِّي ثَلاَثًا . فَقَالَتْ عَائِشَةُ فَقُلْتُ يَا رَسُولَ اللَّهِ أَتَنَامُ قَبْلَ أَنْ تُوتِرَ فَقَالَ " يَا عَائِشَةُ إِنَّ عَيْنَىَّ تَنَامَانِ وَلاَ يَنَامُ قَلْبِي "
قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
