Do they have list with names of all the human beings that existed since inception?
The title of the thread is "What is wrong if human being turn to G-d?" Right, please?
Don't evade the topic - you have mentioned "truthful religion" more than once
Don't run away when challenged
And yes -
there is wrong if humans believe that their "god" is the only way and that "his" dictates are to be followed and try to coerce others in to it. If you believe in your god and leave others alone - then there is probably no issue with it. That is the straightforward answer to your question right there.
Your people (muslims) have a history of massacring those they thought were non believers especially in India over the centuries. So I have serious issues with your outlook about god and to be frank with a supposed religion that purports to dictate every facet of life.
Do not ask stupid questions like lists of names of human beings since inception - it is plain that the Qu'ran as does Genesis refers to the "first created humans about 6000 years ago" that has been proven inaccurate by science many times over. How many "Adam"'s do you know that are referred to as Nabi in the Qu'ran?
