The modern populations of southern Arabia consist of five different MSAL (Modern South Arabic Language) groups such as the Mahra, Shahra, Jibbali, Soqotri, and Harsusi. These populations interact with Arabic-speaking beduin such as the Bait Mashani, Beni Saar and others. At Fasad, at the edge of the Rub al Khali, beduin can be found at numerous springs and wells.
