well, you can get almost everything if you don't care about the law. But if you want to get services legally, then it might be good idea to do it the right way. Those channels you mention, e.g. Iqra,
Aljazeera, the only company that offers those channels is Dishnetwork, and it needs to be described to get them. So they are not free.
However that store owner did it, I don't thinkg its legal.
