A type of sale (bay’) that was particularly popular in the days of early Islam and pre-Islam, where the buyer or the seller of a piece of folded cloth used, in order to execute a sale transaction, to touch that cloth as a sign of finalizing the sale, without ever seeing it. The touch sale is forbidden by shari’a due to the amount of gharar associated therewith (the sale is completed without its underlying object being seen by the buyer).

Touch sale is known in Arabic bay’ al-mulamasah.
