Renting a Property to Open a Café that Serves Hookahs

Question
A property has been rented to open a café that serves coffee, but it has now started serving hookahs. Is the landlord sinful, and is it permissible for him to terminate the rental contract for this reason?
Answer
I say, and with God's success: the sin is on the tenant, not on the landlord; because the wrongdoing was due to his action, and this is not an excuse to terminate the lease. It can only be terminated with the tenant's consent, and God knows best.
