Immutability

Immutability is the state of being unchangeable; an attribute of God alone, since He alone is unchangeable not only in His essence but in the perfection of all His attributes.

Since change implies an imperfection in the sense that something new could be added to the principal, there can be no change in God who is infinitely perfect.  Created things do not have existence of themselves but receive it from God the Creator.  They are dependent upon God’s creative will.

God alone in His existence is absolutely perfect and immutable. (7:50)
