The ruling on taking a Product for Consultation regarding it
Question :
A man took some jewelry from me and said, "I will show it to my family to see if it is suitable for them (i.e., meaning his wife). If it is suitable I will bring you the money for it." What is the ruling on that?
Answer:
If an agreement was not reached between the two parties for buying and selling before he took it to show to his family, and he only took it to show to his family, and if they liked it he would buy it, and if not he would return it, that is allowed. In this case the jewelry is in the hand of the buyer like a trust until the sales agreement is completed, after his family is pleased with it.
