The Prophet (ﷺ) forbade the type of sale which involves risk (or uncertainty) and a transaction determined by throwing stones.
Sunan Abi Dawud Book 23, Hadith 51
← Previous Hadith The Prophet (ﷺ) forbade sale of fruits for a number of years. One of the two narrators (Abu al-Zubair and Sa'id b. Mina') mentioned the words "sale for years" (bai' al-sinin instead of al-mu'awamah).

Sunan Abi Dawud Book 23, Hadith 50 Next Hadith → 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.
