"Somali forces contributed much to the Imām’s victories. Shihāb ad-Dīn, the Muslim chronicler of the period, writing between 1540 and 1560, mentions them frequently (Futūḥ al-Ḥabasha, ed. And trs. R. Besset Paris, 1897). The most prominent Somali groups in the campaigns were the Geri, Marrehān, and Harti – all Dārod clans. Shihāb ad-Dīn is very vague as to their distribution and grazing areas, but describes the Harti as at the time in possession of the ancient eastern port of Mait. Of the Isāq only the Habar Magādle clan seem to have been involved and their distribution is not recorded. Finally, several Dir clans also took part."
