There was no Daarood anywhere near Zeila, in fact most of the Daarood moved from Puntland region around the end of the 1700s . The Isaaq moved into Sanaag before the Daaroods and the Isaaq moved towards Zeila before the Daaroods,
While the main Darod center was Gidaya and Hargaya (the Jigjiga region to north of Harar), there were of course Darod in Zeila, there were all clans in Zeila, it was an economic and political center, the Muqdisho if it's day. Modern Zeila is a ghost town and a ruin, the town was completely destroyed when the Portuguese burned it to the ground in the 1600s. The Turks rebuilt the modern town of Zeila, which has been slowly crumbling ever since. There used to be a ton of Arabs in Zeila who mostly left for Yemen following Somali independence, and a surprisingly large Jewish population who all moved to Israel in the 1960s.
The Adal state was a multi-clan state. Adal had Hawiye, Darod, Dir, Isaaq, Argobba, Cafar and Arabs all living together in one state.
