How can one overcome spiritual apathy and the polytheism of love, and return to the love of Allah after being preoccupied with worldly matters, taking into account the nature of adolescence?

The love of Allah is one of the greatest foundations of faith, and it is the origin of every righteous deed. If the heart is filled with it, the love of everything else becomes secondary to it. Languor is a natural phenomenon, and its cure lies in being certain that there is no power or strength except with Allah, in holding fast to Him, in being keen on good companionship, in avoiding bad company, in frequently remembering death, in contemplating the verses of Allah, in diversifying acts of worship, and in permissible recreation for the soul, along with persistent supplication.
