From this explanation...

From this explanation, it is known that every thing that comes into existence, whether they are the sacred substances of the divine realm, or the natural substances of the realm of mulk, or accidents, whether it is the essences, or attributes, or acts-all of them come into being with the sustainment, sway, and all-inclusiveness of the Divine Power. Hence, the meaning of the statement becomes clear: وَبِقَوَّتِي أَدَّيْتَ فَرَائِضِي.

It is with My Power that you carry out the obligations prescribed by Me. Also, the station of the absolute Will is the same as that of the all-encompassing Mercy ( rahmah ) and the all-inclusive Bounteousness. Hence He has said: وَبِنِعْمَتِي قَوِيتَ عَلَى مَعْصِيَتِي. And it is with My bounty that you obtained the strength to disobey Me.
