It was narrated that Ibn 'Abbas said:"When the Messenger of Allah prayed Tahajjud at night, he would say: "Allahumma lakal-hamd, Anta nurus-samawati wal-ard wa man fihinna. Wa Lakal-hamd . Anta qayyamus-samawati wal-ard wa man fihinna . Wa lakal-hamd , Anta malikus-samawati wal-ard wa man fihinna. Wa lakal-hamd, Antal-haqq, wa'duka haqq, wa liqa'uka haqq, wa qawluka haqq, wal-jannatu haqq, wan-nar haqq, was-sa'atu huqq, wan-nabiyyuna haqq , wa Muhammadun haqq. Allahumma laka aslamtu, wa bika amantu, wa 'alaika tawakkaItu wa ilaika anabtu, wa bika khamastu , wa ilaik a hakamtu, faghfirli ma qaddamtu wama akhkhartu wama asrartu wama a'lantu . Antal-muqaddimu wa Antal-muakhkhiru. Lailaha ilia anta wa la ilaha ghairuka, wa la hawa wala quwwuta illa bika (0 Allah, to You is praise, You are the Light of the heavens and the earth, and everyone therein. To you is praise, you are the Sustainer of the heavens and the earth, and everyone therein. To you is praise, you are the Sovereign of the heavens and the earth, and everyone therein. To You is praise, You are the Truth; Your promise IS true, the meeting with You is true, Your saying is true, Paradise is true, the Fire is true, the Hour is true, the Prophets are true, and Muhammad is true. O Allah, to you have I submitted, in You I believe, in You have I put my trust, to You I turn in repentance, by Your' help I argue, to You I refer my case, so forgive me for my past and future sins, what I have done in secret and what I have done openly. You are the One Who brings forward and puts back. None who has the right to be worshiped but you, and there is none who has the right to be worshiped other than you. And there is no power and nor strength except with you." (Sahih) Another chain that Ibn 'Abbas narrated: "When the Messenger of Allah stood during the night for Tahhajud," and he mentioned something similar.
