Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated that when the Messenger of Allah (peace and blessings be upon him) would get up at night to perform Tahajjud, he would say: O Allah, all praise is for You, for You are the Light of the heavens and the earth. All praise is for You, for You are the Sustainer of the heavens and the earth. All praise is for You, for You are the Lord of the heavens and the earth and whatever is in them. You are true, Your promise is true, and Your word is true, and meeting You is true, Paradise is true, and Hell is true, all the Prophets are true, and the Hour is true. O Allah, I have submitted to You, I have believed in You, I have put my trust in You, I have turned to You, I have argued before You, and I seek judgment from You. So forgive me for all my past and future sins, those I have committed secretly and those I have committed openly. You are my God; there is no god but You.
