Prophet Muhammad is regarded as the final prophet in Islam, born in Mecca around 570 CE. He is known for receiving revelations from Allah through the angel Gabriel, which were later compiled into the Quran, the holy book of Islam. His teachings emphasized monotheism, compassion, and social justice, significantly shaping the beliefs and practices of over a billion Muslims worldwide. Muhammad's life and actions serve as a model for Muslims, and he is often referred to as the 'Seal of the Prophets' for his role in completing the message of previous prophets.
