Yahya related to me from Malik that he had heard that al-Oasim ibn Muhammad said, ''Umar ibn al-Khattab said, 'A dinar for a dinar, and a dirham for adirham, and a sa for a sa. Something to be collected later is not to be sold for something at hand. ' "
Muwatta Malik Book 31, Hadith 35
← Previous Hadith Yahya related to me from Malik from Abdullah ibn Dinar from Abdullah ibn Umar that Umar ibn al-Khattab said, "Do not sell gold for gold except like for like. Do not increase part of it over another part. Do not sell silver for silver except like for like, and do not increase part of it over another part. Do not sell some of it which is there for some of it which is not. If someone asks you to wait for payment until he has been to his house, do not leave him. I fear rama for you." Rama is usury.
