I disagree.
There are honest, devout and god loving Muslims. It has been my privlege to know two of them in the course of my life. They ARE rare - but it would be dishonest of me to say they do not exist. No one said witnessing was easy. I have witnessed two. Should that offend you, so be it.
There is no such thing as an honest, devout and god loving Athiest. A person who rejects god cannot be godly. To borrow a phrase from the muslims, Atheists are haram. It is a more satisfying word than simply evil, with undertones of slime and foulness.
I han’t insult you by dictating, but you have read “The Last Battle” by C. S. Lewis.
If all you’re saying is that Muslims can find the one, true God (after which they are no longer Muslim), then we agree. If you’re saying that Muslims can find God and remain Muslim, then we could not disagree more.
BTW, many an atheist has found God also, but not while remaining an atheist.
