Is it permissible to exchange gold among women without a sale?

Question:
May Allah reward you. Honorable Shaykh, a questioner says: Is it permissible to exchange gold among women without a sale? For example, if a woman says to another, "Will you exchange your bracelet for mine?" Or is it necessary for the weights to be equal between them?

Answer:
This is a sale. Exchanging is a sale, and even if it is not called a sale, it is a sale; because a sale is the exchange of wealth, as the jurists say. Exchanging wealth for wealth is what a sale is. This is a sale, and it requires equality in weight. If the type is the same, equality in weight is necessary, and immediate exchange in the meeting is necessary. If the type differs, such as gold for silver, immediate exchange in the meeting is required, and a difference in amount is permissible. The Messenger (peace and blessings be upon him) said: . Yes.
