‘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.”Shafi'i 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.

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.

Samura b. Jundub told that the Prophet, forbade selling animal for animals when payment was to be made at a later date. Tirmidhi, Abu Da.wud, Nasa’i, Ibn Majah and Darimi transmitted it.

‘Abdallah b. ‘Amr b. al-‘As told that the Prophet commanded him to equip an army, but when the camels were insufficient he commanded him to keep back the young camels of the sadaqa, and he was taking a camel to be replaced by two when the camels of the sadaqa came. Abu Dawud transmitted it.

Usama b. Zaid reported the Prophet as saying, "Credit involves usury.”In a version he said, "There is no usury when payment is made on the spot.”(Bukhari and Muslim.)

‘Abdallah, son of Hanzala who was washed by the angels*, reported God's Messenger as saying, "A dirham which a man knowingly receives in usury is more serious than thirty-six acts of fornication”. Ahmad and Daraqutni transmitted it. * Hanzala was killed at the battle of Uhud. The dead were buried without being washed, and as Hanzala is reputed to have been in a state of ceremonial impurity at the time, his family were anxious; so the Prophet told them he had been washed by the angels. He is commonly called al-ghasil. In the text above the phrase used is ghasil al-mala’ika. Baihaqi transmitted in Shu'ab al-iman on the authority of Ibn ‘Abbas with the addition that he said, "Hell is more fitting for him whose flesh is nourished by what is unlawful.”

Abu Huraira reported God’s Messenger as saying, "Usury has seventy parts, the least important being that a man should marry his mother.”Ibn Majah and Baihaqi, in Shu'ab al-iman

Ibn Mas'ud reported God’s Messenger as saying, "Even though usury be much it leads in the end to penury.”Ibn Majah and Baihaqi, in Shu'ab al-iman, transmitted it, and Ahmad also transmitted it.

Abu Huraira reported God's Messenger as saying, "On the night when I was taken up to heaven I came upon people whose bellies were like houses and contained snakes which could be seen from outside their bellies. I asked Gabriel who they were and he told me that they were people who had practised usury.”Ahmad and Ibn Majah transmitted it.
