A tenant is using my residential house as a meeting point for prostitution. What is your advice?
Normally it is permissible to rent out one’s property to someone who will obviously do some Haraam acts in the house. But that is not the concern of the owner of the house. He rents it out for residential purposes. But when the house is hired specifically for Haraam activities such as the ones mentioned, then it is not permissible and the income is Haraam.
