Selling a box of toys whose
      contents are unknown
Question

                I have a grocery in
      which there is a product which consists of a carton in which are twelve
      boxes. This is called “Try Your Luck” – each box contains candy and
      a child’s toy, either a car, airplane, fan or train. Each box has a
      different toy inside. What is the ruling on selling these things to
      customers?
Praise be to Allah.In
      this kind of product the boxes are sealed and it is not known which kind
      of child’s toy is inside. This is bay’ majhool (selling
      something sight unseen), which lacks the necessary condition of knowledge
      of what is being sold, either by sight or by description. Hence it is not
      permissible to deal with this kind of product where what is being sold is
      not known, either by sight or by description, because it is a kind of
      deceptive sale such as was forbidden in the hadeeth of Abu Hurayrah (may
      Allaah be pleased with him), who narrated that the Prophet 
 (peace and
      blessings of Allaah be upon him) forbade sales of deception. (Narrated by Muslim, 3/1153)
