Q 3:
If a person rents a house, can the tenant sell Khamr (intoxicants) in it?
A:
It is impermissible for a person to rent his house to someone who is known to sell Khamr in it. This is because it is considered a form of cooperation in sin and transgression which Allah (Exalted be He) prohibits in His saying,
...but do not help one another in sin and transgression.
(Surah Al-Ma'idah, 5: 2). If the person who rents the house has no idea about the Khamr but then finds out, he should have the tenant expelled, if he does not stop selling Khamr.
