I want to open up an exercise and recreational room facility in an area where taxi drivers come to wait for passengers. This room will provide for them a place to exercise, eat and a recreational room with pool tables, and other games. Only cab drivers who are already waiting for passengers come to this area, so while they are waiting for passengers they can pass the time at my facility. Presently, if they buy food at a nearby restaurant there is no place to sit and eat, so they either have to stand, sit on the ground or eat in their cars. My concern is that I may be giving them an area to gamble while they are waiting for passengers, but how much am I responsible for their actions?

All praise be to Allah, and may his peace and blessings be on the last and best prophet and messenger, Muhammad.

You are only responsible for the services you provide them. However, if you truly fear that the environment will be unwholesome, then I would recommend for you to find another business.

Allah knows best.
