Ok let me take this one step further. I run a business where we are trying to source Islamic 'fashionable' dresses to sell. Let me assure, I have enough info on this to tell you this is a huge market! Am in the process of launching something along these lines. Will share the same when its ready in half a year or so.
Its pure business my friend. If there is a market and there is a requirement, businessmen will fill that gap. Nothing to do with religious belief or anything of that matter. My partner is a Muslim chap and he is part of the same where we sell Hindu items too
Its nothing but business.
