Abdul Aziz bin Jurayj (may Allah have mercy on him) says that I asked Umm al-Mu'mineen Hazrat Aisha (may Allah be pleased with her) which surahs the Prophet (peace and blessings be upon him) used to recite in Witr. She replied: In the first rak'ah, "Sabbih isma rabbika al-a'la," in the second, "Qul ya ayyuhal kafirun," and in the third, "Qul huwa Allahu ahad," and he would also recite the Mu'awwidhatayn.
