Dua When Starting Tahajjud by MyIslaam

Ibn Abbas narrates that when the Prophet of Allah, Allah send his peace and blessings on him would stand for Tahajjud he would recite the following:

Oh Allah, all praise belongs to You, You are the giver of light to the heavens and earth and all who are in them, for You is all praise, You are the care taker of the heavens and earth and all who are in them, for You is all praise, You are the absolute truth, Your promise is true, Your word is true, Your meeting is definite, Heaven and Hell fire is true, the day of judgement is true, the Prophets are true, Muhammad is true, Oh Allah, only to You I submit, only upon You I rely, only in you I believe, only to You I return, only with your help do I debate, only You do I take as a judge, so forgive all that I have done or will do, all that I do openly and secretly, You are the one who puts (people) ahead and behind, there is none worthy of worship besides You.

عَنْ ابْنِ عَبَّاسٍ

كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا قَامَ مِنْ اللَّيْلِ يَتَهَجَّدُ قَالَ

 اللَّهُمَّ لَكَ الْحَمْدُ أَنْتَ نُورُ السَّمَوَاتِ وَالْأَرْضِ وَمَنْ فِيهِنَّ وَلَكَ الْحَمْدُ أَنْتَ قَيِّمُ السَّمَوَاتِ وَالْأَرْضِ وَمَنْ فِيهِنَّ وَلَكَ الْحَمْدُ أَنْتَ الْحَقُّ وَوَعْدُكَ حَقٌّ وَقَوْلُكَ حَقٌّ وَلِقَاؤُكَ حَقٌّ وَالْجَنَّةُ حَقٌّ وَالنَّارُ حَقٌّ وَالسَّاعَةُ حَقٌّ وَالنَّبِيُّونَ حَقٌّ وَمُحَمَّدٌ حَقٌّ اللَّهُمَّ لَكَ أَسْلَمْتُ وَعَلَيْكَ تَوَكَّلْتُ وَبِكَ آمَنْتُ وَإِلَيْكَ أَنَبْتُ وَبِكَ خَاصَمْتُ وَإِلَيْكَ حَاكَمْتُ فَاغْفِرْ لِي مَا قَدَّمْتُ وَمَا أَخَّرْتُ وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ أَنْتَ الْمُقَدِّمُ وَأَنْتَ الْمُؤَخِّرُ لَا إِلَهَ إِلَّا أَنْتَ

( أَوْ لَا إِلَهَ غَيْرُكَ)

(رواه البخاري: بَاب الدُّعَاءِ إِذَا انْتَبَهَ بِاللَّيْلِ)
