Azerbaijan, officially the Republic of Azerbaijan, is a country in the South Caucasus region of Eurasia at the crossroads of Eastern Europe and Western Asia. It is bounded by the Caspian Sea to the east, Russia to the north, Georgia to the northwest, Armenia to the west and Iran to the south. The exclave of Nakhchivan is bounded by Armenia to the north and east, Iran to the south and west, and has an 11 km (6.8 mi) long border with Turkey in the northwest.
Al-Ash'ath Ibn Qays was appointed by Uthman Ibn Affan as a governor of Azerbaijan. Imam Ali (AS) kept him on his job but directed him to be pious and honest in dealing with the wealth which he receives. When Al-Ash'ath insisted on doing wrong and misusing the wealth of the Muslims, Imam Ali (AS) fired him.
