And the Messenger of Allah, peace and blessings be upon him, forbade two ways of buying and selling and two ways of wearing clothes: (The prohibited ways of wearing clothes are these) that none of you should wrap himself in a single garment in such a way that his private parts are not covered with cloth, and when he prays (in a single sheet), he should wrap it in such a manner that both ends of the sheet are tied on his neck from opposite sides. And the Messenger of Allah, peace and blessings be upon him, forbade making a sale by touching the goods, or by throwing a pebble, and from «بیع بخش» (brokerage sale).
