‘A’isha said that when the Prophet (ﷺ) got up at night he began his prayer by saying, “O God, the Lord of Gabriel, Michael and Israfil, the Creator of the heavens and the earth, who knowest the unseen and the seen, Thou decidest among Thy servants concerning their differences. Guide me on account of different opinions regarding the truth by Thy permission; verily Thou guidest whom Thou wilt to a straight path.” Muslim transmitted it.
