Mishkat al-Masabih, 1192

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

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
