I don't think it is scam, they have open profiles in Linked in, they operate according to shariah norms and they are legit at all.
Today they have a lot of contests in telegram and they are giving out ethereum as well!
DUDE! for real? do you think having an open account will change anything? Following your words, everyone who has no idea in religion can Make an ICO and collect money for own goods. They will never say where did they collect fiat money, They will never show you the smart contract (Just because it is freaking wallet), They sell tokens with 150% bonus, OMG come on!
DO you really think it is the legit project? This Adab Haraam exchange project is a scam...These three team members from Kazakhstan but living in Uzbekistan are
non-denominational Muslims so are not following Shariag. They are claiming to follow Shariah but they are scammers.
Look at their exchange, it looks like something out of 1997 when the internet was relatively new !They have used a couple of widely available plugins to "code" the exchange and a nonsense cms for the website layout template

There is nothing Shariah about this. It is an ordinary looking cheaply available plugin that was not custom coded. It is just enough to show newbies and gullible people that they have a product and will ask for ICO funding from anybody without vetting them which might be including from prostitutes and pimps.
