Firstly you're contradicting yourself. The 16th century is from 1501-1600. According to your logic it was already formed before his death. What small kingdoms competing are you referring to, you don't have a source for that, you made it up it seems. Also where does Mukhtar state anything about Arabs ruling the coast? In fact Mukhtar states that Islam spread from the coast where there was
Somali Muslim centres . Even in his other works he never attributes coastal cities entirely to Arabs like you have. Also your source "Arab factor in Somalia" literally describes Migiurtinia as being under Adal. As you can see they are described as semi-nomadic meaning they have a seafaring tradition and he states it was seemingly formed before the 16th century. Your source you're trying to use to back up your argument supports mine. He also cites I.M. Lewis who agrees with this.
