Musnad Ahmad

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the Prophet (peace and blessings be upon him) would wake up in the middle of the night to pray Tahajjud, he would recite this supplication: «لَكَ الْحَمْدُ أَنْتَ نُورُ السَّمٰوَاتِ وَالْأَرْضِ وَمَنْ فِيهِنَّ وَلَكَ الْحَمْدُ أَنْتَ قَيِّمُ السَّمٰوَاتِ وَالْأَرْضِ وَمَنْ فِيهِنَّ وَلَكَ الْحَمْدُ أَنْتَ مَلِكُ السَّمٰوَاتِ وَالْأَرْضِ وَمَنْ فِيهِنَّ وَلَكَ الْحَمْدُ أَنْتَ الْحَقُّ وَوَعْدُكَ حَقٌّ وَلِقَاؤُكَ حَقٌّ وَالْجَنَّةُ حَقٌّ وَالنَّارُ حَقٌّ وَالسَّاعَةُ حَقٌّ وَمُحَمَّدٌ صَلَّى اللّٰهُ عَلَيْهِ وَسَلَّمَ حَقٌّ وَالنَّبِيُّونَ حَقٌّ اَللّٰهُمَّ لَكَ أَسْلَمْتُ وَبِكَ آمَنْتُ وَعَلَيْكَ تَوَكَّلْتُ وَإِلَيْكَ أَنَبْتُ وَبِكَ خَاصَمْتُ وَإِلَيْكَ حَاكَمْتُ فَاغْفِرْ لِي مَا قَدَّمْتُ وَمَا أَخَّرْتُ وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ أَنْتَ الْمُقَدِّمُ وَأَنْتَ الْمُؤَخِّرُ لَا إِلٰهَ إِلَّا أَنْتَ أَوْ لَا إِلٰهَ غَيْرُكَ» "O Allah! All praise is for You, You are the Light of the heavens and the earth and all that is within them, and all praise is for You, You are the Sustainer of the heavens and the earth and all that is within them, and all praise is for You, You are the King of the heavens and the earth and all creatures between them. You are the Truth, Your word is the truth, Your promise is the truth, meeting You is the truth, Paradise is the truth, Hell is the truth, and the Hour is the truth. O Allah! I submit to You, I believe in You, I rely upon You, I turn to You, I argue by Your power, I make You my judge, so forgive me my past and future sins, those I have done in secret and in public. You are the only One worthy of worship besides whom there is no other."
