Not one single accessible link. Luling isn't in print and is not available on line. If you have a copy, post it. Frankly, I have so far seen no reason to believe her sources. If she says Himyar only traded with the Somali city states, she is clearly wrong.
You are a waste of time. I will not respond to anything else from you without an accessible link.
I've given you references. Use your brain to go to google books.
Himyar had no colonies in the Horn so stop your lies. I've given you Chinese sources stating that the Barbara city states the proto Somalis had kingdoms that claimed supremacy one another and that they were wealthy and powerful with self governance.
Doesn't sound to me like they were ever controlled.
