The mysterious stories of the Shahnameh show that the land of Yemen has been in a political and economic connection with the great Iranian empire for a long time. Although it is called "Hamavaran" in one part and "Yemen" in other parts; it means a single land that extends from the east of the Tigris to the banks of Arabia, Oman, Yemen, and sometimes the Levant. Dahhak was born from Yemen and a black-eyed demon named Zangiyab was known as his grandfather, who oppressed Iranshahr for many years. Fereydun had chosen the daughters of the king of Yemen as his sons' wives, and the rulers of Yemen have always been with Fereydun and Kay Khosrow in the battle against the enemies. The Naqsh-e Rostam inscription in Fars considers Oman and Yemen as part of an Iranian province, which in the Sassanid era was the base of Iranians in competition with the Byzantine government and maintaining their maritime sovereignty. The people who are fed up with the rule of the blacks of Abyssinia extend a helping hand to Khosrow Anushirvan, and the Sassanid horsemen reach the coast of Yemen with ocean-going ships, the Iranian generals become the rulers of Yemen, and their children are considered a privileged generation there, and they create new systems in the affairs of the country and the army, and they learn the Iranian language and culture there, and with emergence of Islam, the children of Iran become the first Muslims in Yemen and extinguish the fire of sedition of a false prophet. They build the first mosque in the garden of the Iranian ruler and gradually become a part of the people there.
