Therefore, if You forgive me, You are already the best of those who show mercy, and If You punish me, You are then not wronging me. Yet, it is Your munificence and Your generosity, O Allah, that gave me the courage to pray You, despite that I have committed things that You dislike. It is Your kindness and mercy that I use as my means during misfortunes inflicting me despite my shamelessness. I thus hope that my expectation will not be disappointed amid these two matters. So, make my hopes become real and answer my prayers. O Greatest Besought One that has been ever besought, and the Most Favorable Hoped One! My expectation, O my Chief, has been great but my deed has been bad. So, grant me Your pardon as much as my expectation,
