What is the ruling on saying "May your house be ruined" to oneself, then uttering "what is your Lord" after the word "Allah" comes to mind, and is this considered a diminishment of Allah's status or an act of disbelief?

Uttering insults against Allah Almighty is apostasy from Islam and leads to Hellfire. A Muslim must guard his tongue, for what comes to mind without being uttered incurs no accountability. The occurrence of such a thought indicates a sickness in the heart that must be treated by glorifying Allah Almighty and striving to alert society to the seriousness of this matter. One should accustom the tongue to goodness and repent from sins.
