What is the ruling on subscribing to cooperative societies, licensed by the state, for the purpose of purchasing a house or a car, where each subscriber pays a sum, and the remaining amount is divided into installments, and a lottery is conducted to determine the turn for receiving the total money from the installments, and the society purchases what the member chooses and places a mortgage on it, and takes a percentage of the money as fees?

It is permissible to establish an association or a fund for purchasing homes and cars through monthly installment payments, where the collected installments are given to one of the subscribers via a lottery. This falls under cooperating in good deeds and is considered cooperative insurance. The fund's money must be invested in a permissible field. It is also permissible for the overseeing authority to take a fee for this, whether it is a fixed amount or a percentage of the money. There is no objection to taking a mortgage from the buyer to guarantee payment of what is due from him.
