‘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.”
Abu Huraira reported God's Messenger as saying, “A time is certainly coming to mankind when only the receiver of usury will remain, and if he does not receive it some of its vapour (or alternatively, its dust) will reach him.”
Ahmad, Abu Dawud, Nasa'i and Ibn Majah transmitted it.
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.
Fadala b. 'Ubaid* said that at the battle for Khaibar he had bought a necklace in which there were gold and gems for twelve dinars, and after considering them separately he found that it was worth more than twelve dinars, so he mentioned that to the Prophet who said, "It must not be sold till the contents are considered separately."
Muslim transmitted it.
* The Damascus edition, iii, 308 and Mirqat, iii, 311 wrongly give Abu 'Ubaid, but in the commentary Mirqat gives the name correctly as Fadala b. 'Ubaid.
