Sayyiduna Abdullah bin Hanzalah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "One dirham of usury is a more severe sin in the sight of Allah Almighty than committing adultery thirty-six times by mistake."

Abu Sa'id al-Khudri (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) sold a free man who had become destitute.

Abdur Rahman bin Mut’im narrates: My business partner bought some dirhams on credit, so I said:“This is not correct.”The man replied:“I have sold this in the market and no one objected to it.”The narrator says: I asked Sayyiduna Bara’ bin ‘Azib about this, and he stated that when the Prophet Muhammad (peace be upon him) came to Madinah, we used to make such transactions, so the Prophet said:“There is no harm in transactions that are hand to hand, but those that are on credit are not permissible.”“You should meet Sayyiduna Zayd bin Arqam and ask him, for he is the most knowledgeable among us regarding matters of trade.”The narrator says: When I asked him about this, he also said the same thing.

Shaykh Abu Minhal narrates from Sayyiduna Bara’ and Sayyiduna Zayd bin Arqam, they say: During the blessed time of the Prophet Muhammad (peace be upon him), we used to trade. We asked the Prophet (peace be upon him) about the exchange of currency (bay‘ sarf). He said:“If it is hand to hand, then there is no harm; if it is on credit, then it is not permissible (i.e., if dirhams or dinars are being exchanged from both sides).”

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) and Sayyiduna Abu Hurairah (may Allah be pleased with him) narrate: The Noble Prophet (peace and blessings be upon him) sent Sayyiduna Suwad bin Ghaziyyah, who belonged to Banu 'Adi, and appointed him as the overseer of Khaybar. He used to bring fine dates from there. The Noble Prophet (peace and blessings be upon him) asked: "Are all the dates of Khaybar like this?" He replied: "No, O Messenger of Allah, by Allah! I have bought one sa' in exchange for two sa' and two sa' in exchange for three sa' of good dates." The Noble Prophet (peace and blessings be upon him) said: "Do not do so. Rather, first sell them, then buy (the good dates) with their price. Do the same with all things that are weighed." Imam Daraqutni (may Allah have mercy on him) says: Every type of date whose specific name is not determined is called 'jum'a', as in: 'There is jum'a (i.e., various types of dates) in so-and-so's land.'

This same narration is also transmitted with another chain of narration from Abdul Aziz bin Muhammad bin Abdul Majeed bin Suhail.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "That thing which is weighed should be equal when both types are the same, and when something is measured, it should also be the same way. But when the types on both sides are different, then there is no harm in it." This narration is also transmitted from Sayyiduna Anas (may Allah be pleased with him) from the Noble Prophet (peace and blessings be upon him) through other chains of transmission.

Shaykh Abu Ash'ath narrates: He was present in the sermon of Sayyiduna Ubadah bin Samit (may Allah be pleased with him), he narrates: I heard him stating that the Prophet Muhammad (peace and blessings be upon him) said: "Gold is to be sold for gold, but only equal in weight, and silver for silver, but only equal in weight, whether it is in its original form or in the form of coins. Then he commanded the sale of barley for barley, wheat for wheat, dates for dates, and salt for salt, and then he explained that there is no harm in exchanging wheat for barley, as long as it is hand to hand and there is an excess in one, but this transaction must be hand to hand. In any other case, whoever gives or takes more, he will be engaging in usury." The narrator named Abdullah states: I narrated this hadith to my father, and he considered it good.
