اللّهُـمَّ رَحْمَتَـكَ أَرْجـو 
فَلا تَكِلـني إِلى نَفْـسي طَـرْفَةَ عَـيْن، 
وَأَصْلِـحْ لي شَأْنـي كُلَّـه 
لَا إِلَهَ إِلَّا أنْـت
Allāhumma raḥmataka arjū 
falā takilnī ilā nafsī ṭarfata `ayn, 
wa aṣliḥ lī sha'nī kullah, 
lā ilāha illā ant.


O Allah, I hope for Your mercy. 
Do not leave me to myself even for the blinking of an eye (i.e. a moment). 
Correct all of my affairs for me. 
There is none worthy of worship but You.
