Garaad diinle
There are some who claim decent from him two in particular there might be more though. They're dhagkawe and barkhadle.That's not valid evidence if there's nobody that claims to descend from them, besides samaale's originated in modern day eastern Ethiopia. So why would that son specifically be on the other side of the horn.
They've even been mentioned by caydarus himself and he did mention where they were found in his time.
And about xamar ibn samaale some of his branches are the people of dhagkawe and the people of barakatle and they live in the land of barawe all the way to lamo with the tunni.
