Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) forbade "jalab" and "janab"; he forbade the touch-sale (mulamasah) and false bidding (najash) in a sale; and he forbade that a man should buy over his brother's sale or propose marriage over his brother's proposal. (Al-Haythami says:) I say: Abu Dawud and others recorded this part of it: "There is to be no jalab and no janab." Its narrators are the narrators of the Sahih.
