O mother, inform me about the prayer of the Messenger of Allah ﷺ. She said: His (night prayer) in Ramadan and (during other months) was thirteen rak'ahs at night including two rak'ahs of fajr.
أَتَيْتُ عَائِشَةَ فَقُلْتُ أَىْ أُمَّهْ أَخْبِرِينِي عَنْ صَلاَةِ رَسُولِ اللَّهِ ﷺ فَقَالَتْ كَانَتْ صَلاَتُهُ فِي شَهْرِ رَمَضَانَ وَغَيْرِهِ ثَلاَثَ عَشْرَةَ رَكْعَةً بِاللَّيْلِ مِنْهَا رَكْعَتَا الْفَجْرِ
