Sunan at-Tirmithiy كتاب الصلاة باب ما جاء كيف النهوض من السجود
حَدَّثَنَا إِسْحَاقُ بْنُ مُوسَى الأَنْصَارِىُّ حَدَّثَنَا مَعْنٌ حَدَّثَنَا مَالِكٌ عَنْ سَعِيدِ بْنِ أَبِى سَعِيدٍ الْمَقْبُرِىِّ عَنْ أَبِى سَلَمَةَ أَنَّهُ أَخْبَرَهُ أَنَّهُ سَأَلَ عَائِشَةَ كَيْفَ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم بِاللَّيْلِ فِى رَمَضَانَ فَقَالَتْ مَا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَزِيدُ فِى رَمَضَانَ وَلاَ فِى غَيْرِهِ عَلَى إِحْدَى عَشْرَةَ رَكْعَةً يُصَلِّى أَرْبَعًا فَلاَ تَسْأَلْ عَنْ حُسْنِهِنَّ وَطُولِهِنَّ ثُمَّ يُصَلِّى أَرْبَعًا فَلاَ تَسْأَلْ عَنْ حُسْنِهِنَّ وَطُولِهِنَّ ثُمَّ يُصَلِّى ثَلاَثًا. فَقَالَتْ عَائِشَةُ فَقُلْتُ يَا رَسُولَ اللَّهِ أَتَنَامُ قَبْلَ أَنْ تُوتِرَ فَقَالَ يَا عَائِشَةُ إِنَّ عَيْنَىَّ تَنَامَانِ وَلاَ يَنَامُ قَلْبِى. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ.
Abū-Salamah asked 'Ā'ishah what the prayer of the Messenger of God, peace and blessings of God be upon him, was like at night during Ramadan. She replied, "The Messenger of God, peace and blessings of God be upon him, did not exceed, in Ramadan or otherwise, eleven units of [voluntary night] prayer. He would pray four units, and do not ask about their perfection and length. Then, he would pray [another] four, and do not ask about their perfection and length. Then, he would pray three." 'Ā'ishah then said, "So I asked, 'Messenger of God, do you sleep before you pray the [voluntary] odd-numbered prayer[1] ?' He replied, ''Indeed, Ā'ishah, my eyes sleep, but my heart does not sleep.'
[1]The voluntary night prayer that ends a person's worship for that day, and is performed in an odd number of prayer units (one unit, three units, etc.).
