Abu Dawud

Narrated Abu Hurairah: The Prophet ﷺ forbade the type of sale which involves risk (or uncertainty) and a transaction determined by throwing stones.

Narrated Abu Saeed Al Khudri: The Prophet ﷺ forbade two types of business transactions and two ways of dressing. The two types of business transactions are mulamasah and munabadhah. As regards the two ways of dressing, they are the wrapping of the Samma, and that when a man wraps himself up in a single garment while sitting in such a way that he does not cover his private parts or there is no garment on his private parts.

The tradition mentioned above has also been reported by Abu Saeed al-Khudri from the Prophet ﷺ through a different chain of narrators. This version adds: "Wearing the Samma means that a man puts his garment over his left shoulder and keeps his right side uncovered. Munabadhah means that a man says (to another): If I throw this garment to you, the sale will be certain. Mulamasah means that a man touches it (another's garment) with his hand and neither he unfolds it nor turns it over. When he touched it, the sale becomes binding.

The tradition mentioned above has also been transmitted by Abu Said al-Khudri through a different chain of narrators from the Messenger of Allah ﷺ to the same effect as narrated by both Sufyan and Abd al-Razzaq.

Narrated Ibn Umar: The Messenger of Allah ﷺ forbade the transaction called habal al-habalah.

A similar tradition has also been narrated by Ibn Umar from the Prophet ﷺ through a different chain of transmitters. He said: Habal al-habalah means that a she-camel delivers an offspring and then the offspring which it delivers becomes pregnant.
