It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The one who takes usury (riba) and the one who gives it are equal (in sin)." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "A dinar for a dinar and a dirham for a dirham (must be equal), with no excess between them. Whoever needs silver should exchange gold for it on the spot, and whoever needs gold should exchange silver for it on the spot; and this exchange must be hand to hand and on the spot." This hadith is gharib (singular) and sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it with this wording.
