What is the required action if a buyer sells an item under an option stipulation for a profit before the condition expires?

Primary text

If a buyer purchases an item with a stipulation and sells it for a profit before the condition expires, they must return it to the owner if the owner demands it. If the buyer cannot return it, the seller is entitled to the value of the item because their property was consumed, or they may reach a settlement (Musalaha) with the buyer. The requirement to return the item is conditional upon the owner's demand.
