What is the ruling of Sharia on the wealth of an owner of a commercial building leased to a café that serves cigarettes and shisha, whether the shisha is from the forbidden pipe or from manufactured fruit materials? Is he sinful for that? Is he obliged to cancel the existing lease contracts? What should he do if the laws protect the tenants and he cannot cancel the contracts?

Renting out shops for selling forbidden items such as alcohol and shisha is impermissible and the contract must be annulled, as it constitutes aiding in sin. Allah has forbidden this, saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." The majority of jurists consider a rental contract invalid if it explicitly states in the agreement that it is for a sinful purpose. However, if this is not specified, the contract is valid, and the renter is obligated to use the property for permissible activities. If the landlord is coerced into approving the tenant's forbidden acts, there is no sin upon him. Selling the rented property does not necessitate the annulment of the rental agreement.
