دعاء السجود
سُبْحَانَ رَبِّيَ الأَعْلَى ثلاث مرَّاتٍ.
Glory be to my Lord, the Most High. (Three times.)
سُبْحَانَكَ اللَّهُمَّ رَبَّنَا وَبِحَمْدِكَ، اللَّهُمَّ اغْفِرْ لِي.
Glory be to You, O Allah, our Lord, and praise be to You. O Allah, forgive me.
سُبوحٌ، قُدُّوسٌ، رَبُّ الْمَلَائِكَةِ وَالرُّوحِ.
Most Perfect, Most Holy, Lord of the angels and of the Spirit (Jibril).
اللَّهُمَّ لَكَ سَجَدْتُ وَبِكَ آمَنْتُ، وَلَكَ أَسْلَمْتُ، سَجَدَ وَجْهِيَ لِلَّذِي خَلَقَهُ، وَصَوَّرَهُ، وَشَقَّ سَمْعَهُ وَبَصَرَهُ، تَبَارَكَ اللَّهُ أَحْسنُ الْخَالِقينَ.
O Allah, for You I have prostrated, in You I have believed and to You I have submitted. My face has prostrated before the One who created it, shaped it and opened its hearing and its sight. Blessed be Allah, the best of creators.
سُبْحَانَ ذِي الْجَبَرُوتِ، وَالْمَلَكُوتِ، وَالْكِبْرِيَاءِ، وَالْعَظَمَةِ.
Glory be to the Possessor of all power, sovereignty, greatness and majesty.
اللَّهُمَّ اغْفِرْ لِي ذَنْبِي كُلَّهُ: دِقَّهُ وَجِلَّهُ، وَأَوَّلَهُ وَآخِرَهُ، وَعَلاَنِيَّتَهُ وَسِرَّهُ.
O Allah, forgive me all my sins: the small and the great, the first and the last, the open and the hidden.
اللَّهُمَّ إِنِّي أَعُوذُ بِرِضَاكَ مِنْ سَخَطِكَ، وَبِمُعَافَاتِكَ مِنْ عُقوبَتِكَ، وَأَعُوذُ بِكَ مِنْكَ، لاَ أُحْصِي ثَنَاءً عَلَيْكَ، أَنْتَ كَمَا أَثْنَيْتَ عَلَى نَفْسِكَ.
O Allah, I seek refuge in Your pleasure from Your anger, in Your pardon from Your punishment, and I seek refuge in You from You. I cannot count Your praises: You are as You have praised Yourself.
