اَللَّهُمَّ إِنِّي عَبْدُكَ وَابْنُ عَبْدِكَ وَابْنُ أَمَتِكَ، نَاصِيَتِي بِيَدِكَ، مَاضٍ فِيَّ حُكْمُكَ، عَدْلٌ فِيَّ قَضَاؤُكَ، أَسْأَلُكَ بِكُلِّ اسْمٍ هُوَ لَكَ، سَمَّيْتَ بِهِ نَفْسَكَ، أَوْ أَنْزَلْتَهُ فِي كِتَبِكَ، أَوْ عَلَّمْتَهُ أَحَدًا مِنْ خَلْقِكَ، أَوِ اسْتَأْثَرْتَ بِهِ فِي عِلْمِ الْغَيْبِ عِنْدَكَ، أَنْ تَجْعَلَ الْقُرْآنَ رَبِيْعَ قَلْبِي، وَنُوْرَ بَصَرِيْ (وَنُورَ صَدْرِي)، وَجَلَاءَ حُزْنِيْ، وَذَهَابَ هَمِّيْ

Allaahumma 'innee 'abduka, wabnu 'abdika, wabnu 'amatika, naasiyatee biyadika, maadhin fiyya hukmuka, 'adlun fiyya qadhaa'uka, 'as'aluka bikulli ismin huwa laka, sammayta bihi nafsaka, 'aw 'anzaltahu fee kitaabika, 'aw 'allamtahu 'ahadan min khalqika, 'aw ista'tharta bihi fee 'ilmil-ghaybi 'indaka, 'an taj'alal-Qur'aana rabee'a qalbee, wa noora basaree (in another narration it is 'sadree' instead of 'basaree'), wa jalaa'a huznee, wa dhahaaba hammee

O Allah, I am Your slave and the son of Your male slave and the son of your female slave. My forehead is in Your Hand (i.e. you have control over me). Your Judgment upon me is assured and Your Decree concerning me is just. I ask You by every Name that You have named Yourself with, revealed in Your Book, taught any one of Your creation or kept unto Yourself in the knowledge of the unseen that is with You, to make the Qur'an the spring of my heart, and the light of my chest, the banisher of my sadness and the reliever of my distress. [1] Abdullah ibn Mas’ud (RA) said, The Messenger of Allah (ﷺ) said, “If anyone afflicted with anxiety, inquietude state and he says the above mentioned dua, then Allah will remove his distress and anxiety and altered it with happiness. Companions then said, ”So, we have to learn these words! He said,“Obviously! Whomsoever listens to these words, should memorize them.” This hadith's chain of narration is acceptable. [2] N.B. Women should say this dua like this: “Allaahumma inni amatuka, wa bintu ‘abdika wa bintu amatika….” Meaning: “Oh Allah! I am your slave girl, a daughter of your slave and a daughter of your slave girl….” In many hadiths, it is encouraged to make dua by the greatest name of Allah. In many narrations, it is said that if anyone ask Allah by this name then Allah will accept his dua.
