In the holy book of Islam, how many surahs (chapters) are there?

Dude, no! Please, don't bring "us" into it (titles etc. too). Try writing the explanation as if you would for an encyclopedia; just the necessary and the sufficient; enlightening and informative without being zealous/emotional/opinionated. Thank you.

Are the “social issues of the emerging Muslim community “ different ways to kill people of other faiths?
