اَللَّهُمَّ رَبَّ السَّمَوَاتِ السَّبْعِ وَرَبَّ الْأَرْضِ، وَرَبَّ الْعَرْشِ الْعَظِيمِ، رَبَّنَا وَرَبَّ كُلِّ شَيْءٍ، فَالِقَ الْحَبِّ وَالنَّوَى، وَمُنْزِلَ التَّوْرَاةِ وَالْإِنْجِيلِ، وَالْفُرْقَانِ، أَعُوْذُ بِكَ مِنْ شَرِّ كُلِّ شَيْءٍ أَنْتَ آخِذٌ بِنَاصِيَتِهِ، اَللَّهُمَّ أَنْتَ الْأَوَّلُ فَلَيْسَ قَبْلَكَ شَيْءٌ، وَأَنْتَ الْآخِرُ فَلَيسَ بَعْدَكَ شَيْءٌ، وَأَنْتَ الظَّاهِرُ فَلَيْسَ فَوْقَكَ شَيْءٌ، وَأَنْتَ الْبَاطِنُ فَلَيْسَ دُونَكَ شَيْءٌ، اقْضِ عَنَّا الدَّيْنَ وَأَغْنِنَا مِنَ الْفَقْرِ

Allaahumma Rabbas-samaawaatis-sab'i wa Rabbal ard, wa Rabbal-'Arshil-'Adheem, Rabbanaa wa Rabba kulli shay 'in, faaliqal-habbi wannawaa, wa munzilat-Tawraati wal-'Injeeli, wal-Furqaan, 'a'oodhu bika min sharri kulli shay 'in 'Anta 'aakhidhun binaasiyatihi. Allaahumma 'Antal-'Awwalu falaysa qablaka shay'un, wa 'Antal-'Aakhiru falaysa ba'daka shay'un, wa 'Antadh-Dhaahiru falaysa fawqaka shay'un, wa 'Antal-Baatinu falaysa doonaka shay'un, iqdhi 'annad-dayna wa 'aghninaa minal-faqr

O Allah, Lord of the seven heavens and the Lord of the Earth and Lord of the Magnificent Throne, our Lord and Lord of all things, Splitter of the seed and the date stone, Revealer of the Towraat, the Injeel and the Furqaan, I take refuge in You from the evil of all things You shall seize by the forelock. O Allah, You are The First so there is nothing before You and You are The Last so there is nothing after You. You are ath-Dhaahir so there is nothing above You and You are al-Baatin so there is nothing closer than You. Settle our debt for us and spare us from poverty. Abu Huraira (RA) reported that Allah's Messenger (ﷺ) used to command us that as we go to our bed, we should utter the words (as mentioned above). In another narration, he said that when Fatima (RA) asked him for a khadima, he then taught the dua.
