Sahih al-Bukhari Book 34, Hadith 96
Allah's Messenger (ﷺ) forbade the selling by Munabadha, i.e. to sell one's garment by casting it to the buyer
not allowing him to examine or see it. Similarly he forbade the selling by Mulamasa. Mulamasa is to
buy a garment, for example, by merely touching it, not looking at it.
Allah's Messenger (ﷺ) forbade the sale called 'Habal-al-Habala which was a kind of sale practiced in the Pre- Islamic Period of ignorance. One would pay the price of a she-camel which was not born yet would be born by the immediate offspring of an extant she-camel.
The Prophet (ﷺ) forbade two kinds of dressing; (one of them) is to sit with one's legs drawn up while wrapped in one garment. (The other) is to lift that garment on one's shoulders. And also forbade two kinds of sale: Al-Limais and An-Nibadh.
