Is deceit allowed in Islam to spread the religion?

[Minimalist]

Anything that postulates an invisible sky-daddy with no evidence to back it up is a lie.

Lying implies intent. It can't simply be about saying things that aren't true, since that applies to just about everything they say.

If they are knowingly putting out falsehoods about their own religion, book or whatever, that's pretty sad in the first place. It's often entirely pointless too since it's never been easier to fact check things. You're not likely to fool anyone who doesn't already believe the same thing.

But no, lying to get attention to the club is not unique to the koran. Paul in the bible has a verse in that book of the NT says "If through my falsehood" .... meaning if lying gets Jesus and God attention then it is all good.

I looked it up, and what you're saying is a common misconception. In context, Paul is actually condemning such behavior.
