It is a religious obligation that so few Arabs pursue, which resulted in God's judgement inflicted upon them; there is even no escape for them in whatever way they ally themselves with satan, hence, paralyzed with mysticism, savagery, ignorance, discontinuous dispersion and diffusion allover the surface of the planet.
Linguistically and Geographically ALL Semites were and are Arabs. Historically ALLpure Arabs come from Yemen and descend from one Yemenite father; and politically the rest of the impure Arabs including those from the ancient dwellers in Iraq known as, Adnaanis, descend from prophet Abraham, peace be upon him.
Religious FACT: All people of earth descended from Arabs, including the historical figure of the Yemenite father of today's Arabs along with Abraham, peace be upon him, himself.
