It is narrated from Sayyiduna Abu Sa'id Khudri, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, forbade two types of garments and two types of transactions. (The mention of garments is in another place.) The two transactions are: one is Munabadhah and the other is Mulamasah. Munabadhah is when a person says: When I throw this cloth towards you, the deal will be finalized. And Mulamasah is when a person touches the cloth, without trying it on or turning it over; as soon as he touches it, the deal is finalized.
