The following are Mustahab in connection with sale and purchase:
- One should not discriminate between various buyers while charging for the
commodities, except in the case of poor people.
- One should not be adamant about the prices, unless one feels that one is
being duped or cheated.
- One should give a little more of the thing one sells, and should take a
little less of the thing which one buys.
- If the buyer regrets having purchased something, and wishes to return it,
the seller should accept it back.
