Allah has not made us to be socially useful, He has made us to worship Him. Worship means that our fascination is with His attributes, that we regard Him as Significant, and that we recognize that all that is good and beneficial in our lives comes from Him and all that is harmful comes from ourselves.
Being worshipful means to understand that we are fundamentally unable to be useful to either ourselves or others, and that when things go right and succeed it is because He made it so. In so far as we have been designed to the end of being worshipful it means that this capacity to act unconditionally and leave the outcomes to Him is the highest aspect of ourselves.
The deen is a vehicle to establish this transformation of being fascinated with our selves, our own consequence and significance to His.
