Sayyiduna Malik bin Aws (may Allah be pleased with him) narrates: He wanted to exchange one hundred dinars. He says: Sayyiduna Talhah bin Ubaidullah (may Allah be pleased with him) called me, and we both agreed on the transaction. He completed the exchange with me and took the gold, turning it over in his hand. He said: My clerk comes from the forest (Ghābah), (then I will pay you). Sayyiduna Umar bin Khattab (may Allah be pleased with him) heard this. Sayyiduna Umar (may Allah be pleased with him) said: By Allah, you will not separate from him until you receive it from him. Then Sayyiduna Umar (may Allah be pleased with him) informed that the Prophet (peace and blessings of Allah be upon him) said: "Exchanging gold for silver is usury except when it is hand to hand; exchanging wheat for wheat is usury except when it is hand to hand; exchanging dates for dates is usury except when it is hand to hand; exchanging barley for barley is usury except when it is hand to hand."

Sayyiduna Abu Bakrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings of Allah be upon him) forbade selling silver for silver or gold for gold, except if it is equal (in amount, then it is permissible), and the Prophet (peace and blessings of Allah be upon him) commanded that gold may be sold for silver as one wishes, or silver for gold as one wishes.

(Imam Ibn Hibban, may Allah have mercy on him, says:) The statement of the Prophet (peace and blessings of Allah be upon him): "as one wishes" means: when the transaction is hand to hand.

Abu Washa’ah narrates: Previously, people used to buy and sell with silver vessels from the spoils of war until they received their salaries. Then Sayyiduna ‘Ubadah informed that the Prophet Muhammad (peace be upon him) forbade exchanging gold for gold, silver for silver, wheat for wheat, barley for barley, dates for dates, and salt for salt, except when it is equal for equal and hand to hand. Whoever gives more or demands more, he will be engaging in usury.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: The Prophet (peace and blessings of Allah be upon him) said: "Sell gold for gold only in equal amounts; do not make one side more than the other. Sell silver for silver only in equal amounts; do not make one side less than the other. And do not sell any of these present items for something that is absent."

Nafi’ reports: A man informed Sayyiduna Abdullah bin Umar (may Allah be pleased with them) that Sayyiduna Abu Sa’id Khudri (may Allah be pleased with him) had narrated this hadith from the Prophet Muhammad (peace and blessings be upon him). Nafi’ reports: Then Sayyiduna Abdullah bin Umar (may Allah be pleased with them) and that man set out, and I was with them. Until we reached Sayyiduna Abu Sa’id Khudri (may Allah be pleased with him), Sayyiduna Abdullah bin Umar (may Allah be pleased with them) said to Sayyiduna Abu Sa’id Khudri (may Allah be pleased with him): Are you aware of the hadith that this man has narrated to me? Did you narrate that report from the Prophet Muhammad (peace and blessings be upon him)? Did you hear this from the Prophet Muhammad (peace and blessings be upon him) himself? Sayyiduna Abu Sa’id Khudri (may Allah be pleased with him) asked: What is that matter? So Sayyiduna Abdullah bin Umar (may Allah be pleased with them) said: The narration regarding selling gold for gold and silver for silver. Then Sayyiduna Abu Sa’id Khudri (may Allah be pleased with him) pointed with his fingers towards his eyes and ears and stated: My eyes saw this and my ears heard the Prophet Muhammad (peace and blessings be upon him) when he said this:“Sell gold for gold only in equal amounts. Do not pay less on either side. And sell silver for silver only in equal amounts. Do not pay less on either side. And do not sell something absent for something present among them.”

Sayyiduna Ubadah bin Samit (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Gold for gold, silver for silver, wheat for wheat, barley for barley (the exchange) must be equal and hand to hand. When their types differ, then sell as you wish, provided it is hand to hand."

Sayyiduna Malik bin Aws (may Allah be pleased with him) narrates: I went out with one hundred dinars. I met Sayyiduna Talhah bin Ubaidullah (may Allah be pleased with him), who was sitting in the shade of a wall. He agreed on the price with me and said that when his servant would come from Ghabah, he would make the payment. Sayyiduna Umar (may Allah be pleased with him) heard this. He inquired about it from Sayyiduna Talhah (may Allah be pleased with him), so he explained: There are some dinars (which I am buying), and I intend that when my servant comes from Ghabah, (then I will make the payment). Sayyiduna Umar (may Allah be pleased with him) said: Do not separate from him, do not separate from him until you have paid him. The Prophet (peace and blessings of Allah be upon him) said: Exchanging gold for silver is usury, except when it is hand to hand; exchanging wheat for wheat is usury, except when it is hand to hand; exchanging barley for barley is usury, except when it is hand to hand; exchanging dates for dates is usury, except when it is hand to hand.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: Fresh dates were brought, and the dates of the Prophet (peace be upon him) were of another kind, some of which were dry. The Prophet (peace be upon him) inquired, "Where did these come from?" The people replied, "We bought one sa' of these in exchange for two sa' of our dates." The Prophet (peace be upon him) said, "Do not do this, this is not correct. Rather, sell your dates (for something else), and then buy what you need with that (thing)."

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) and Sayyiduna Abu Hurairah (may Allah be pleased with him) narrate: The Prophet (peace and blessings of Allah be upon him) appointed a man as the supervisor of Khaybar. That man brought dates of excellent quality, so the Prophet (peace and blessings of Allah be upon him) asked, "Are all the dates there of this kind?" He replied, "No, O Messenger of Allah (peace and blessings of Allah be upon him)! By Allah, we obtained one sa' of these in exchange for two sa' of other dates, and two sa' in exchange for three sa'." So the Prophet (peace and blessings of Allah be upon him) said: "Do not do so. Sell the dates for dirhams, then buy the good quality dates with the dirhams."

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: A man brought Barni dates to the service of the Prophet (peace and blessings of Allah be upon him). The Prophet (peace and blessings of Allah be upon him) asked, "Where did these come from?" He replied, "I bought one sa' of these in exchange for two sa'." The Prophet (peace and blessings of Allah be upon him) said, "Alas, this is pure usury. Do not do this."
