The Azd settlers in Oman are descendants of Nasr bin Azd, a branch of Nabataeans, and were later known as "the Al-Azd of Oman". Seventy years after the first Azd migration, another branch of Alazdi under Malik bin Fahm, the founder of Kingdom of Tanukhites on the west of Euphrates, is believed to have settled in Oman. According to Al-Kalbi, Malik bin Fahm was the first settler of Alazd. He is said to have first settled in Qalhat. By this account, Malik, with an armed force of more than 6000 men and horses, fought against the Marzban, who served an ambiguously named Persian king in the battle of Salut in Oman and eventually defeated the Persian forces. This account is, however, semi-legendary and seems to condense multiple centuries of migration and conflict into a story of two campaigns that exaggerate the success of the Arabs. The account may also represent an amalgamation of various traditions from not only the Arab tribes but also the region's original inhabitants. Furthermore, no date can be determined for the events of this story.
