When making the supplication of Dhul-Nun, should one say, "There is no god but You; glory be to You, indeed I have been of the wrongdoers," and then mention their need, or is it sufficient to say it with the intention of fulfilling the need?

"The Supplication of Dhul-Nun" is: "There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers." This supplication delivers believers from hardships and sorrows. It is considered a du'a (supplication) because it is an affirmation of Allah's Oneness and His transcendence, and an acknowledgment of sin. It opens the door to supplication, and it is recommended to begin a du'a with it, then mention one's need.
