"‏ اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ، أَنْتَ قَيِّمُ السَّمَوَاتِ وَالأَرْضِ، وَلَكَ الْحَمْدُ أَنْتَ رَبُّ السَّمَوَاتِ وَالأَرْضِ وَمَنْ فِيهِنَّ، وَلَكَ الْحَمْدُ أَنْتَ نُورُ السَّمَوَاتِ وَالأَرْضِ وَمَنْ فِيهِنَّ، أَنْتَ الْحَقُّ، وَقَوْلُكَ الْحَقُّ، وَوَعْدُكَ الْحَقُّ، وَلِقَاؤُكَ الْحَقُّ، وَالْجَنَّةُ حَقٌّ، وَالنَّارُ حَقٌّ، وَالسَّاعَةُ حَقٌّ، اللَّهُمَّ لَكَ أَسْلَمْتُ، وَبِكَ آمَنْتُ، وَعَلَيْكَ تَوَكَّلْتُ، وَإِلَيْكَ خَاصَمْتُ، وَبِكَ حَاكَمْتُ، فَاغْفِرْ لِي مَا قَدَّمْتُ وَمَا أَخَّرْتُ، وَأَسْرَرْتُ وَأَعْلَنْتُ، وَمَا أَنْتَ أَعْلَمُ بِهِ مِنِّي، لاَ إِلَهَ إِلاَّ أَنْتَ ‏"

Whenever the Prophet (ﷺ) offered his Tahajjud prayer, he would say, "O Allah, our Lord! All the praises are for You; You are the Keeper (Establisher or the One Who looks after) of the Heavens and the Earth. All the Praises are for You; You are the Light of the Heavens and the Earth and whatever is therein. You are the Truth, and Your saying 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. O Allah! I surrender myself to You, and believe in You, and I put my trust in You (solely depend upon). And to You I complain of my opponents and with Your Evidence I argue. So please forgive the sins which I have done in the past or I will do in the future, and also those (sins) which I did in secret or in public, and that which You know better than I. None has the right to be worshipped but You."
