It was narrated from Ibn 'Abbas that the Messenger of Allah (ﷺ) used to say, when he got up to pray in the middle of the night:

“O Allah, to You be praise, You are the Light of the heavens and the earth. To You be praise, You are the Sustainer of the heavens and the earth. To You be praise, You are the Lord of the heavens and the earth and everyone in them. You are the Truth, Your promise is true, Your Word is true, the meeting with You is true, Paradise is true, Hell is true, the Hour is true. O Allah, to You I have submitted, in You I have believed, in You I repent, by Your help I have disputed, to You I refer for judgement. So forgive me my past and future sins, what I have done secretly and openly. You are the One besides Whom there is no other god.”
