Allah has no likeness, but an example may be used to make a matter understandable.
An example draws on something familiar to illuminate an aspect of the intended meaning. It does not make the two things identical in essence or attributes.
Mawlana Ashraf Ali Thanawi used an illustration of two sheets of paper and glue to explain nearness to Allah. Its purpose is to clarify nearness, not to establish an actual likeness to Allah.
