There is no such things, most of them are haraamis. so just avoid them all for your good health. Dont trust on their fake attair. They speak always positive side, and hiding one million negative sides that will never give u anything good. Even their salaries have no baraka, some of them got 100000/- bonus alone this year, but it disappear the same way it came with no significance to their life. That is what i mean by baraka.
