Is it permissible to sell two apartments to an association that grants loans with known interest to young people, given the dire need for the sale price to repay debts?

It is impermissible to sell a property to an entity known to use it for a forbidden activity, such as lending with interest (riba), whether this is explicitly stated in the contract or understood through circumstantial evidence. However, if the entity will use it for a permissible purpose, it is permissible to sell it to them. The seller is not harmed by the entity's involvement in riba, as long as the transaction between the seller and the entity is Islamically valid.
