What is the ruling on saying: "Allah is stubborn, He is not challenged," with evidence?

This statement is false and forbidden, because obstinacy is a blameworthy trait, meaning defiance of the truth despite knowing it. Allah, glory be to Him, has the Most Beautiful Names and the Most Exalted Attributes. "The Obstinate" is not among His Names, nor is "obstinacy" among His attributes. His Names are beautiful, and His attributes are perfect. One must be careful not to name or describe Allah in a way that is unfitting for Him. This falls under deviation regarding His Names, which is straying from the truth concerning them. Among its types are: denying the Names or Attributes, or likening Allah to His creation, or naming Him with what He has not named Himself, or deriving names for idols from His Names.
