What is the ruling on renting and leasing a coffee shop, even though the landlord stipulated that he would not take rent from shisha but from regular drinks, and that he is not responsible for shisha?

It is not permissible to rent a shop to someone who sells shisha, or uses it for any forbidden purpose, even if the shop is used for permissible matters. This is because the landlord is a partner with the tenant in sin due to their cooperation in disobedience, and the rent the landlord receives is unlawful. Allah Almighty says: "And cooperate not in sin and aggression. And fear Allah; indeed, Allah is severe in penalty." (Al-Ma'idah: 2). Jurists have explicitly stated the prohibition of selling grapes to someone who will use them to make wine, and renting a house to someone who will use it for forbidden purposes, due to the assistance this provides in what Allah has forbidden.
