The dry and harsh climate of Arabia significantly influenced the spread of Islam by shaping the nomadic lifestyle of its people, which facilitated trade and communication across vast distances. The Arabian Peninsula's arid conditions led to the establishment of trade routes that connected different tribes and regions, allowing for the rapid dissemination of Islamic teachings.
