Qutayba ibn Muslim
During the Arab conquest of Iran, the Abd al-Qays migrated to Iran in large numbers and carried out extensive raids in southern Iran. Sizable groups of them settled down in Tavvaz near Dalaki in Bushehr Province. In the early 8th century, 4,000 Abd al-Qays warriors accompanied Qutayba ibn Muslim on his campaign into Khorasan in Iran.
