Is joking with words like "insha'Allah" (God willing) when something is impossible, or "alhamdulillah" (praise be to God) after something bad happens, considered disbelief if not intended as mockery?

The enquirer must discard the obsessive thoughts related to the issue of mockery, because dwelling on them leads one into confusion, doubt, and distress. Joking without intending to mock Allah is not disbelief. These obsessive thoughts must be ignored.
