Djinn and trinity

Even if someone rejected that Djinn exist then he that person would still remain muslim.

Also the belief in the djinn is not like the pagan belief of the trinity which became the belief of salvation. Is that right or not? It amazes me that the entire salvation of the Christans is based not on actual clear evidence but on unclear methaphor.

Its like if a text said the door is ajar then someone said you have to believe that the door is a jar and if you don't then you are going to hell.

So this is what you base salvation on? unclear methaphor?
I base my salvation on the belief of the prophets because my belief and their belief is the same.
