Is it permissible to rent out rooms in one's home via electronic platforms that stipulate not to refuse tenants based on religion or behavior (such as drinking alcohol or not being married), and is this rental considered haram money?

It is permissible to rent out an apartment purchased through murabaha. However, it is not permissible to rent it to someone who will use it for sinful acts, such as selling alcohol, prostitution, or for unmarried couples.

It is permissible to rent accommodation to an atheist, unless it is known that they will use it as a place to spread atheism. However, renting it to a woman who will live in the same apartment without segregation is not permissible due to the possibility of unlawful seclusion (khalwa).

It is permissible to rent the apartment to a non-Muslim, even if it is highly probable that they will drink alcohol or eat pork in it, because these are acts they are allowed to perform in their own lands, unlike adultery.

It has been narrated from Ibn Taymiyyah, Ibn al-Qayyim, al-Buhuti, al-Sarakhsi, and others, that renting something to someone who will commit sins in it is not permissible if the landlord knows or strongly suspects this, as it constitutes aiding in sin. However, if the tenant rents it for a permissible purpose and then commits sin therein, the sin is on them.
