Is salary of a person who install parabol halal?

Answer

Wa alaikumus salaam warahmatullahi wabarakaatuh. Normally when something can be used in different ways, both in Halal and Haraam, so installing and repairing of such device can be tolerated to certain extent, unless it is used predominantly in Haraam ways. As far as parabol is concerned, in our opinion it is installed widely for activities not conforming to Shariah. So in the light of the above we advise you to abstain. However you may query again if you have any important information which did not mention or perhaps we may be not aware of.
