The Islamic religion was brought to India in 1000 A.D by the Afghanistan invaders. One of the most popular and widely followed religions, Islam was founded by Prophet Muhammad in Arabia, about 1,400 years back. With the advent of Mughal rule, Islam flourished in India. The sacred places in India are the Masjids or Mosques and tombs of the Islamic Prophets and Saints. The Jumma Masjid in Delhi is the largest mosque in India and was built by the Emperor Shah Jahan. The relics of the Prophet, his sandals and his footprints are considered sacred.
