"Oh my God, I am heartfully sorry for having offended the Prophet, and I detest those sins because I have offended Thee my God, who is all good and deserving of my love.
I deserve and cherish thy punishment and invite more, until the occasion that I am able by Thy grace and the Grace of the Prophet Knoth to sin no more."
