Narrated Abu Sa`id: Allah's Apostle 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.

Narrated Abu Huraira: The Prophet forbade two kinds of sales i.e. Al-Limais and An-Nibadh (the former is a kind of sale in which the deal is completed if the buyer touches a thing, without seeing or checking it properly and the latter is a kind of a sale in which the deal is completed when the seller throws a thing towards the buyer giving him no opportunity to see, touch or check it) and (the Prophet forbade) also Ishtimal-As- Samma' and Al-Ihtiba' in a single garment.
