Yahya related to me from Malik from Musa ibn Abi Tamim from Abu'l Hubab Said ibn Yasar from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "A dinar for a dinar, a dirham for a dirham, no excess between the two."
Muwatta Malik Book 31, Hadith 29
← Previous Hadith Yahya related to me from Malik that Yahya ibn Said said, "The Messenger of Allah, mayAllah bless him and grant him peace, ordered the two Sads to sell a vessel made of either gold or silver from the booty. They either sold each three units of weight for four units of weight of coins or each four units of weight for three units of weight or coins. The Messenger of Allah, may Allah bless him and grant him peace, said to them, 'You have taken usury, so return it.' "

Muwatta Malik Book 31, Hadith 28 Next Hadith → Yahya related to me from Malik from Nafi from Abu Said al-Khudri that the Messenger of Allah, may Allah bless him and grant him peace, said, "Do not sell gold for gold except like for like and do not increase one part over another part. Do not sell silver for silver, except like for like and do not increase one part over another part. Do not sell some of it which is not there for some of it which is."
