H.A. MacMichael (1988). A History of the Arabs in the Sudan. Cambridge University Press. pp. 89–90 with footnotes., Quote: "HADAHID. (...) As is usual in north-central Africa from east to west they are held in general contempt and the rest of the population do not intermarry with them. This feeling of aversion towards the workers in iron is strongest among the Zaghawa, who so far from intermarrying with them would not eat or associate with them. They are a hereditary caste and are called Miro by the Fur."
