Muhammad Prophet was born in 570 CE, in a small town in Arabia. Around 610 CE he founded Islam. Some people didn't like Islam so they forced Muhammad and his followers to flee to Medina in 622 CE. Within 10 years, the Prophet won considerable support and had a devoted army with him. When Muhammad died in 632 CE, all of Arabia had converted to Islam. Therefore, Arabia submitted to Islam around 632 CE.
