This duaa is narrated by the Prophet (sal Allahu alayhi wa sallam) as one of the “Da’waat al Makroob“, the supplications of the distressed.

اللَّهُمَّ رَحْمَتَكَ أَرْجُو فَلَا تَكِلْنِي إِلَى نَفْسِي طَرْفَةَ عَيْنٍ وَأَصْلِحْ لِي شَأْنِي كُلَّهُ لَا إِلَهَ إِلَا أَنْتَ
Allahumma rahmataka arju fala takilni ila nafsi tarfata ‘aynin wa aslih li sha’ni kullahu la ilaha ila anta

O Allah, it is Your mercy that I hope for, so do not leave me in charge of my affairs even for a blink of an eye, and rectify for me all of my affairs. None has the right to be worshiped except You.
