Is joking about the Istikhara prayer considered a mockery of it that necessitates apostasy, and what are the implications of that?

"Merely advising a colleague to perform Istikhara is not mockery of the religion. The cure for obsessive thoughts (waswas) is to completely ignore them, especially those related to faith and doubts about leaving it, as the default state is that a servant remains Muslim until there is certain proof to the contrary. Scholars have mentioned that whoever utters words that could indicate apostasy or something else is not excommunicated by them, and that the mufti and the judge act in a way that keeps a Muslim within Islam, even if there are ninety-nine indications that might lead to their excommunication."
