Reports on currency exchange

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him), Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) and Sayyiduna Abu Hurayrah (may Allah be pleased with him) used to forbid "bay' al-sarf" (currency exchange); two of them reported this from the Prophet (peace and blessings be upon him) as a "marfu'" hadith.
Ahmad and Abu Ya'la recorded it, and its narrators are the narrators of the Sahih.

Abu Qilabah narrates: People used to buy gold for silver on credit until the time they received their stipends. Hisham bin Amir came to them, forbade them from doing so and said: The Prophet (peace and blessings be upon him) forbade us from selling silver for gold on credit, and he also told us that this is usury.
Ahmad and Abu Ya'la recorded it; Ahmad's narrators are the narrators of the Sahih.

Sayyiduna Abu Rafi' (may Allah be pleased with him) narrates: I went out with anklets, wanting to sell them, because my family needed money for expenses. I saw Sayyiduna Abu Bakr (may Allah be pleased with him), and he asked: Where are you going? I said: My family needs money for expenses, so I intend to sell these two anklets. He said: I too have come out with some dirhams, and I want to get finer silver than them in exchange. The narrator says: He put the anklets in one pan of the scale and the dirhams in the other pan, and the pan with the anklets was somewhat heavier than the one with the dirhams. So Sayyiduna Abu Bakr (may Allah be pleased with him) called for shears. I said: Subhan Allah, this much (must shears be called for such a small bit of silver?) It is yours. He said: Even if you leave it, Allah Almighty will not leave it. I heard the Prophet (peace and blessings be upon him) say: "Gold for gold is to be exchanged like for like, and silver for silver like for like; the one who pays extra and the one to whom extra is paid will both go to Hell."
Al-Bazzar and Abu Ya'la recorded it. Al-Bazzar's chain contains a narrator, Hafs bin Abi Hafs; Imam al-Dhahabi says: He is not strong. Abu Ya'la's chain contains a narrator, Muhammad bin al-Sa'ib al-Kalbi; we seek refuge in Allah from the vile things that have been attributed to him.

Shurahbil bin Sa'd narrates: Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), Sayyiduna Abu Hurayrah (may Allah be pleased with him) and Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrated this hadith. The Prophet (peace and blessings be upon him) said: "Gold for gold is to be exchanged like for like, and silver for silver like for like, and on both sides coin for coin (on the spot). Whoever gives extra or seeks extra has engaged in usury (riba)." Shurahbil said: If I did not hear this from them, may Allah Almighty enter me into Hell. (Allamah al-Haythami says:) I say: A hadith from Sayyiduna Abu Hurayrah (may Allah be pleased with him) and Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) is in the "Sahih".
Ahmad recorded it. The narrator Shurahbil bin Sa'd was declared thiqah (trustworthy) by Ibn Hibban, and the majority of the imams called him da'if (weak).

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: I asked the Prophet (peace and blessings be upon him): May I buy gold for silver, or silver for gold? The Prophet (peace and blessings be upon him) said: "When you buy one of them for the other, then when your counterpart parts from you there should be no ambiguity between you and him." (Allamah al-Haythami says:) I say: A hadith from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) is in the Sunan, that he used to sell camels for silver and take possession of the silver.
Ahmad recorded it, and its narrators are the narrators of the Sahih.

Sayyiduna Abu Rafi' (may Allah be pleased with him) narrates: I used to do goldsmith's work for the wives of the Prophet (peace and blessings be upon him), and they told me that they heard the Prophet (peace and blessings be upon him) say: "Gold for gold and silver for silver are to be exchanged weight for weight. Whoever gives extra or seeks extra has engaged in usury (riba)."
Ahmad recorded it; its chain contains a narrator, Yahya al-Bakka', who is da'if (weak).

Sayyiduna Anas (may Allah be pleased with him) and Sayyiduna Ubadah (may Allah be pleased with him) narrate: The Prophet (peace and blessings be upon him) said: "Gold for gold is to be exchanged like for like, and silver for silver like for like." (Allamah al-Haythami says:) I say: The hadith of Sayyiduna Ubadah (may Allah be pleased with him) is in the "Sahih".
Al-Bazzar recorded it; its chain contains a narrator, al-Rabi' bin Sabih, whom Abu Zur'ah and others declared thiqah (trustworthy), while a group called him da'if (weak).

Sayyiduna Abu Bakrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) forbade bay' al-sarf (currency exchange) two months before his passing. (Allamah al-Haythami says:) I say: In the "Sahih" it is reported from him
that the Prophet (peace and blessings be upon him) forbade exchanging gold for gold, and no date is mentioned in it (as to how long before his passing he did so).
Al-Bazzar recorded it; its chain contains a narrator, Bahr bin Kaniz al-Saqqa', who is da'if (weak).

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) says: Gold for gold is to be exchanged weight for weight; whoever gives extra or seeks extra has engaged in usury. The narrator says: By Allah! Sayyiduna Abdullah bin Umar did not narrate anything false from the Prophet (peace and blessings be upon him).
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its narrators have been declared trustworthy, and there is criticism of some of them that does no harm.

Bishr bin Harb narrates: I asked Sayyiduna Abdullah bin Umar (may Allah be pleased with them both): May I take one dirham for two dirhams? He said: This is usury itself (riba); do not even go near it. Do you not know what the Prophet (peace and blessings be upon him) said? He (peace and blessings be upon him) said: Exchange like for like.
Al-Tabarani recorded it in al-Mu'jam al-Kabir. The narrator Bishr bin Harb is da'if (weak), and he has been given a soft (weak) declaration of trustworthiness.

Abu al-Ma'arik narrates: A man from Ghafiq was owed one hundred dinars by a man from Mahrah. This was in the time of Sayyiduna Uthman (may Allah be pleased with him). They gained some spoils of war, and the man from Mahrah said: I will pay you seventy dinars right away on the condition that you write off the hundred for me, since the payment of those one hundred dinars was not yet due. The man from Ghafiq agreed to this. Sayyiduna al-Miqdad (may Allah be pleased with him) passed by the two of them, and that man took hold of the bridle of his animal to stop him, then told him the whole matter. He said: Both of you have declared war against Allah Almighty and His Messenger.
Al-Tabarani recorded it in al-Mu'jam al-Kabir. I have not found anyone who gives a biography of Abu al-Ma'arik, except that Imam al-Mizzi mentioned him in the biography of Ayyash bin Abbas and named him Ali Abu al-Ma'arik al-Wadi. The rest of the narrators of this report are the narrators of the Sahih.

Sa'd bin Iyas narrates: Sayyiduna Abdullah (may Allah be pleased with him) used to permit exchanging one dirham for two dirhams and one dinar for two dinars. Then he went to Madinah, where he met Sayyiduna Umar (may Allah be pleased with him), Sayyiduna Ali (may Allah be pleased with him) and other Companions of the Prophet (peace and blessings be upon him), and they forbade him from doing so. When he came back, I saw him going round the money-changers and saying: Woe to you! O people! Do not consume usury (riba), and do not buy one dirham for two dirhams or one dinar for two dinars.
Al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are the narrators of the Sahih.
