Is there anything prohibited or mocking in the saying, "I do not want it to be a sin for me to guide others to evil in my head"?

What happened is not mockery or ridicule; rather, it is a whisper (waswasa) that should be ignored. Not all laughter is mockery, for mockery is tinged with disdain and belittlement. Al-Baydawi said: "Al-istihza' (mockery) is sarcasm and belittlement."
