History.
Lineage.
Sheikh Ishaaq ibn Ahmed was one of the Arabian scholars that crossed the sea from Arabia to the Horn of Africa to spread Islam around 12th to 13th century. He is said to have been descended from Prophet Mohammed's daughter Fatimah. Hence the Sheikh belonged to the Ashraf or Sada, titles given to the descendants of the prophet. He married two local women in Somaliland that left him eight sons, one of them being Muhammad (Arap). The descendants of those eight sons constitute the Isaaq clan-family.
Along with the other constituent sub-clans of the Habr Magaadle confederation (including Garhajis, Habr Awal and Ayub), the Arap too took part in the conquest of Abyssinia under the Adal Sultanate. The Habar Magaadle are known for producing a historical figure known as "Ahmad Gurey bin Husain", who was the right-hand man of Ahmad ibn Ibrahim al-Ghazi.
Role in the SNM.
Baligubadle, which straddles the border between Ethiopia and Somaliland, was the headquarters of the Somali National Movement (SNM) during the liberation of Somaliland from the regime of general Siad Barre. 
The Araps were heavily involved the SNM. For example, Hassan Isse Jama was one of original founders of the SNM in London. He was also the first vice president of Somaliland and served as the deputy chairman of the SNM. Furthermore in 1983, Sultan Mohamed Sultan Farah of the Arap clan was the first sultan to leave Somalia to Ethiopia and openly cooperate with the SNM. The Araps were the first clan to disarm their militia (the 10th division under Guutada Sheekh Sancaani) and hand over their weapons after the liberation of Somaliland. Sultan Mohamed sultan Farah agreed to lead the process of demobilization. This put pressure on other clans to follow suit, and, in early 1994, a well-staged ceremony was held in the Hargeysa football stadium to hand over weapons.
The Arap clan is divided into the following sub-clans:
