Arabic hadith text
وَعَنْ مَسْرُوقٍ قَالَ: سَأَلْتُ عَائِشَةَ عَنْ صَلَاةِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِاللَّيْلِ. فَقَالَت: سبع وتسع وَإِحْدَى عشر رَكْعَة سوى رَكْعَتي الْفجْر. رَوَاهُ البُخَارِيّ
Translation

Masruq said he asked ‘A’isha what prayers God’s Messenger said during the night and she replied, “Seven, nine, and eleven rak'as apart from the two rak'as of the dawn prayer.” Bukhari transmitted it.
