"What did the Prophet Muhammad (saw) used to invoke Allah (swt) to say in the night?"
      Narrated Ibn 'Abbas:                          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 (i.e. I worship none but      You)."     Narrated Sufyan:     (regarding the above narration) that the Prophet added, "You are the      Truth, and Your Word is the Truth."
