In the early 600s, a new religious and political force arose out of the deserts of Arabia. Islam, spearheaded by Prophet Muhammad ﷺ, quickly became the way of life for the entire Arabian Peninsula within a few years of the first revelations. By the end of the reigns of the first four caliphs, the Islamic realm extended from Libya in the West to Persia in the East. And just 100 years after the death of Prophet Muhammad ﷺ, Muslims had expanded the empire into Spain and India.
