On these lands of the Arabian Peninsula, lived, obviously, Arabians. Now, I know an amount of information of Arabians, so I answered some FAQs (Frequently Asked Questions). Here are two:

Were all the Arabians Islamic?

No, some were Jewish, and others were Christian, which created the fact that the Arabian Peninsula was monotheistic.

Were there trade routes?

Yes and a large network of trades developed over the two empires that came into the tree continents of Africa, Asia and Europe. Along these trade routes, they sold metal, grain, incense, ivory, perfumes, silk, spices, and textiles.
