The Messenger of Allah ﷺ forbade two ways of wearing a garment, the Samma, and that a man sit with his knees drawn up in a single garment with nothing covering his private parts. He also forbade buying by merely touching an item, buying by throwing a garment to the other party, selling standing grain for measured grain, and selling dates still on the palm for dried dates.
وبإسناده أن رسول الله ﷺ نهى عن لبستين الصماء وأن يحتبي الرجل بثوبه ليس على فرجه منه شيء وعن الملامسة والمنابذة والمحاقلة والمزابنة
