I wanted to know does the thing we learn in schools and collages that our universe is created because of big bang. I wanted to know does islam support this believe and what's islam point of visw on hiw universe began?
Yes, it does, the Qur'an says,
"the heavens and the earth were joined together as one unit, before We clove them asunder" (21:30)
One unit means the start, "singularity" in the big bang theory, all that was was joined as a unity, then Allah clove them asunder, i.e. the big bang (blast) itself.
So in my opinion, this verse clearly does talk about the big bang.
as we know in big bang, the universe created by a very big explosion from a small dot then becomes very big.
in Quran (holy book for islam religion) there is a verse say "the heavens and the earth were joined together as one unit, before We clove them asunder" (21:30)
and after explode, as we know the universe getting bigger. Is already mention in quran in (51:47) We have made the heavens with Our own hands and We expanded it.
