Sahih al-Bukhari Book 34, Hadith 97
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.
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 selling by Mulamasa and Munabadha.
