22 – On the authority of ʿAbd Allāh, from Ibn ʿUmar (may Allah be pleased with them both), the Prophet ﷺ said, “Whoever cheats in buying and selling is not one of us.”

Hammād, narrating from his father and from Abū Sulaymān, said: “The first person to mint the dīnār (gold coin) was Tubbaʿ—namely Asʿad ibn Karb; the first to mint the dirham (silver coin) was Tubbaʿ the Younger; and the first to strike the fulūs (copper coins) and set them in circulation among the people was Nimrūd ibn Kanʿān.”
