Yep, I know but according to Arab historians they claim the other way around and I think a lot of scholars were of the opinion that the Qahtanis were the originals who taught Nabi Ismail. But modern archeology and anthropology points to the North, especially Jordan and Southern Syria. I even mentioned Arab Romans like Philip the Arab who actually hailed from what is now modern Syria.The Qahtanis and other Southern Arabians are actually Arabized Arabs. The History of early Arabic speakers lies in the Northern part of the Arabian peninsula and the Levant.
