Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) forbade two types of sales, two types of clothing, and from munabadhah and mulamasah.

Imam Darimi (may Allah have mercy on him) said: The sale of munabadhah is that the seller throws (a cloth or something similar) towards the buyer and the buyer throws towards the seller (and the sale is considered complete by this act). This was a method of buying and selling in the pre-Islamic era.
