What is the ruling on a charitable organization investing in a gas station that is sublet to workers who sell cigarettes, magazines, and pornographic images? And in this case, does the sin fall only on the investor? What is the Sharia directive regarding one who rents out his shops to those who sell cigarettes, or to barbers, or to shisha cafes?

If an association leases a place to someone for a permissible use, and then the tenant subleases it to someone who conducts an activity that is entirely or partially forbidden, there is no sin upon the association; the sin is upon the tenant. However, the association must prevent him from doing so. If the association knows that the tenant intends to use the premises for something forbidden, such as selling cigarettes or shisha, it is not permissible to lease it to him. Whoever does so is sinful because they are cooperating in sin and aggression. There is no objection to leasing premises to barbers, newspaper vendors, beneficial magazine vendors, and the like, even if they incidentally involve some minor, unintended forbidden elements.
