Duas for sincere repentance and turning back to Allah
O Allah, I am Your servant, son of Your servant, son of Your maidservant. My forelock is in Your hand. Your command over me is ever effective. Your decree concerning me is just. I ask You by every Name that You have named Yourself with, or revealed in Your Book, or taught to any of Your creation, or have kept unto Yourself in the knowledge of the unseen. I ask that You make the Qur'an the springtime of my heart, and the light of my chest, the banisher of my grief, and the reliever of my worries.
O Allah, I seek refuge in You from associating anything with You that I know, and I seek Your forgiveness for what I do not know.
Our Lord, we have wronged ourselves, and if You do not forgive us and have mercy upon us, we will surely be among the losers.
O Allah, forgive me my mistakes, my ignorance, my extravagance in my affairs, and whatever You know better than I. O Allah, forgive me my jesting and my seriousness, my unintentional and intentional sins, my resolve and my jesting; and all of that is with me.
O Allah, I seek refuge in You from the hardship of affliction, the attainment of wretchedness, the evil of decree, and the rejoicing of enemies.
I seek refuge in Allah from the accursed Satan.
O Allah, I seek refuge in You from the cessation of Your blessings, the reversal of Your well-being, the suddenness of Your punishment, and all of Your displeasure. And I seek refuge in You from the hardship of tribulation, the attainment of misery, the evil of fate, and the rejoicing of enemies. And I seek refuge in You from the demolition of buildings, the fall of spears, and the biting of the path.
O Allah, forgive me for all my sins, the small and the great, the first and the last, the apparent and the hidden. And repair my shortcomings with it, and pay off my debts for me. O Allah, I ask You for guidance, piety, chastity, and richness.
O Allah, forgive my every sin, the minor and the major, the first and the last, the open and the secret. O Allah, You are the First, before Whom nothing is; You are the Last, after Whom nothing is; You are the Apparent, above Whom nothing is; You are the Hidden, closer than whom nothing is. Settle our debts for us and enrich us from poverty.
O Allah, I seek refuge in You from the evil of my soul, and from the evil of every creature You are seizing by its forelock. I seek refuge in You from the evil of envy, hatred, and stinginess.
O Allah, forgive me for my sin, all of it, the minor and the major, the first and the last, the open and the secret, my companions and my errors.
O Allah, forgive me for what I have done in the past and what I will do in the future, what I have done in secret and what I have done openly, what I have exceeded in, and what You know better about me. You are the One Who brings forth and the One Who delays. There is no god but You.
