It shouldn’t be said but it can’t be considered to be true Kufr unless it is meant by the heart. However, it is a very serious offense and can nullify Islam if a person persists to say it.

Statements that are uttered these days such as if someone says when praising something or someone “I worship this or that” ..Naudhubillah or “XYZ is like a footballing god” Naudhubillah, can they be regarded as statements of Kufr?
