Dua in the morning & evening: Say once

يَا حَيُّ يَا قَيُّوْمُ بِرَحْمَتِكَ أَسْتَغِيْثُ أَصْلِحْ لِي شَأْنِيْ كُلَّهُ وَلَا تَكِلْنِيْ إِلَى نَفْسِيْ طَرْفَةَ عَيْنٍ

Yaa Hayyu yaa Qayyoomu birahmatika 'astagheethu 'aslih lee sha'nee kullahu wa laa takilnee 'ilaa nafsee tarfata 'aynin

O Ever Living, O Self-Subsisting and Supporter of all, by Your mercy I seek assistance, rectify for me all of my affairs and do not leave me to myself, even for the blink of an eye. Anas (RA) said, The Messenger of Allah (ﷺ) told Fatima (RA) that,"I advice you that, you should supplicate this in the morning and evening"
