Sa'id b. al-Musayyib told in mursal form that God’s Messenger forbade the sale of meat for animals1. Sa'id said it was connected with the maisir2 of the people of pre-Islamic times.
It is transmitted in Sharh as-sunna.
1. i.e. meat sold in exchange for living animals.
2. A game of chance played with arrows for parts of a camel. The type of transaction mentioned in the tradition is evidently considered to contain something in the nature of a gamble.
Sa'd b. Abu Waqqas said he heard God's Messenger being asked about buying dry dates for fresh and asking whether the fresh dates were diminished when they became dry. On being told that they were, he forbade that.
Malik, Tirmidhi, Abu Dawud, Nasa’i and Ibn Majah transmitted it.
‘Ubada b. as-Samit reported God’s Messenger as saying, “Do not sell gold for gold, or silver for silver, or wheat for wheat, or barley for barley, or dates for dates, or salt for salt except equal for equal, kind for kind, payment being made on the spot; but sell gold for silver, silver for gold, wheat for barely, barley for wheat, dates for salt and salt for dates, payment being made on the spot, as you wish.”
