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

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

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.
