Islam (Arabic: الإسلام) is the second-largest religion in India, with 14. 2% of the country’s population or approx. 200 million people identifying as adherents of Islam (2018 estimate). It makes India the country with the largest Muslim population outside Muslim-majority countries. The majority of Indian Muslims belong to Sunni sect of Islam while the Shia form a sizeable minority. Islam first came to the western coast of India when Arab traders as early as the 7th century CE came to coastal Malabar and Konkan-Gujarat. Cheraman Juma Mosque in Kerala is thought to be the first mosque in India, built in 629 CE by Malik Deenar. Following an expedition by the governor of Bahrain to Bharuch in the 7th century CE, immigrant Arab and Persian trading communities from South Arabia and the Persian Gulf began settling in coastal Gujarat. Ismaili Shia Islam was introduced to Gujarat in the second half of the 11th century, when Fatimid Imam Al-Mustansir Billah sent missionaries to Gujarat in 467 AH/1073 CE.
