Allah (SWT) is The Sustainer … Nothing can exist or develop, grow or change except that it happens through Allah (SWT).
Also, to maximise how we understand the Power of Allah (SWT) - He can Create the whole Universe through Kun … This means “all of what we see” CAN instantly come in to place. The fact that it did not come in to place exactly how we see it - is not less amazing - because each moment is expressly from the Kun. It is not enough to assume that only the changes are being managed by Allah (SWT) - even the ongoing constancy of the existence of things is being managed by Allah (SWT).
