The Prophet used to invoke Allah at night, saying, “O Allah: All the Praises are for You: You are the Lord of the Heavens and the Earth. All the Praises are for You; You are the Maintainer of the Heaven and the Earth and whatever is in them. All the Praises are for You; You are the Light of the Heavens and the Earth. Your Word is the Truth, and Your Promise is the Truth, and the Meeting with You is the Truth, and Paradise is the Truth, and the (Hell) Fire is the Truth, and the Hour is the Truth. O Allah! I surrender myself to You, and I believe in You and I depend upon You, and I repent to You and with You (Your evidences ) I stand against my opponents, and to you I leave the judgment (for those who refuse my message). O Allah! Forgive me my sins that I did in the past or will do in the future, and also the sins I did in secret or in public.You are my only God (Whom I worship) and there is no other God for me (ie I worship none but You). “- Sahih Bukhari 9/93/482. Narrated Ibn ‘Abbas.
