What is the ruling on a Muslim renting an apartment or house that he owns to a kaafir, knowing that this kaafir will most likely drink alcohol in the house, or eat pork, or observe some kaafir religious practices?
Praise be to Allaah.
Imaam al-Sarkhasi (may Allâh have mercy on him) said: there is nothing wrong with a Muslim renting his house to a Dhimmi (Jew or Christian living under Islamic law) to live in. If he drinks wine there or worships the cross, or brings pork into the house, there is no sin on the Muslim for that because he did not rent the house to him for that purpose. The sin is on the renter who does that, as he does it without any intention on the part of the landlord, so there is no sin on the landlord. (Al-Mabsoot, 16/39).
