Is the phrase "There is no deity except You; glory be to You. Indeed, I was of the wrongdoers" considered a formula for seeking forgiveness, and can it be adopted as a regular litany for seeking forgiveness?

The saying, "There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers," is a supplication of praise that includes a request for forgiveness. These words are called a supplication because they contain two types of prayer: a supplication of praise and a request. His saying, "There is no deity except You," is an acknowledgment of monotheism, and his saying, "Indeed, I have been of the wrongdoers," is an acknowledgment of sin, which implicitly includes a request for forgiveness. A servant can repeat this supplication at any time or adopt it as a regular recitation without being restricted to a specific time or number.
