Is a booklet containing the word of Allah (Jalalah) inside it exposed to desecration when it is closed?

What you have mentioned does not constitute a desecration of the name of Allah the Almighty. We advise you not to dwell on whispers of apostasy. Be keen to ask about what benefits you in your worship and leave what is of no benefit. For the Companions used to ask about practical matters that benefited them, not about hypothetical scenarios or complex issues.
