The monetary system of Muslims in Iran until the end of the Umayyad rule

In this study, which has been compiled as a library, an attempt has been made to examine the attitude of Muslim Arabs towards the monetary system of Iran, which was the main basis of the Sassanid financial system. Historical narrations show that the second caliph, considering the lack of Arab history in government and financial affairs, accepted the Iranian financial system and made adjustments to bring it in line with Islam. In the financial system inherited from Muslims, money and coins are of great importance. It was because in addition to facilitating trade, it would gain the wealth of the Islamic Caliphate, so the Islamic caliphs minted the Sassanid coins again with a few changes in the name of the Sassanid Arabs, and until 1977, when Abdul Malik minted the first independent Islamic coin, The east was the same Sassanid Arab coins, and from this year onwards, independent Islamic coins were minted in the lands of the Islamic Caliphate in the east and west, and of course each caliph made changes to its design and role, and perhaps these coins are called He himself became famous.
