|The oldest mosques are oriented to Dedan|
The highest concentration of Old Arabic texts has been found in the region of Dedan. Genesis 10:7 tell us that Dedan the Elder was a grandson of Kush by his son Raamah. Raamah was Nimrod's brother. Raamah settled in the region to the southeast of Dedan while Nimrod built a kingdom in the Tigris-Euphrates River Valley. Genesis reveals a kinship connection between the Afro-Arabian Dedanites and the Afro-Asiatic Arameans. The separation of the two groups in the time of Peleg and Joktan was territorial only, as the ruling lines continued to intermarry.
Dedan the Younger was the son of Abraham's first-born son Joktan (Gen. 25:3). Most Arabs are descended from Abraham through Joktan. He is remembered by Arabs as Yaqtan. Josephus knew him as Joctan and his name is preserved in the ancient town of Jectan near Mecca.
