What are the sayings and deeds, other than prayer, fasting, and lowering one's gaze, that greatly please Allah, Glorified and Exalted Be He?

Allah, the Exalted, rejoices intensely at the repentance of His servant, as narrated in the prophetic tradition about the man who lost his riding animal with his food and drink on it, and then found it, so he rejoiced greatly. This divine joy indicates the greatness of Allah's mercy and His love for His servant's return to Him, not His need for our repentance. Allah truly rejoices, but not like the rejoicing of created beings; it is a joy befitting His Noble Self. This joy motivates the servant to repent and return to Allah whenever he sins, just as Allah rejoices at the obedience of the obedient and the good deeds of the doers of good.
