What is the hearth region of Islam?

The hearth region of Islam is the Arabian Peninsula, specifically the area surrounding Mecca and Medina in present-day Saudi Arabia. This region is significant as it is the birthplace of the Prophet Muhammad and the site of key events in early Islamic history. Mecca, home to the Kaaba, is regarded as the holiest city in Islam, while Medina is where Muhammad established the first Muslim community. Together, these cities played a crucial role in the development and spread of the Islamic faith.
