Conditions for Sellers and Buyers
2089. There are six conditions to be fulfilled by the seller and the buyer:
First: They should be Baligh.
Second: They should be sane.
Third: They should not be feeble-minded, that is, they should not be squandering off their wealth.
Fourth: They should have an intention to sell and purchase. Hence, if a person says in jest that he has sold his property, that transaction is void.
