Religion
According to the 2006 estimate by the U.S. Department of State, roughly 98% of the population in Comoros are Muslim. Islam and its institutions have helped to integrate Comorian society and provide identification with a world beyond the island's shores. Most adherents are Arab-Swahili or Persian, but there are also people of Indian descent.
Comorians follow religious observances conscientiously and strictly adhere to religious orthodoxy. During colonization, the French did not attempt to supplant Islamic practices and were careful to respect the precedents of sharia as interpreted by the Shafi'i school of thought.
Christianity in Comoros is a minority religion. Roman Catholics in Comoros are about 6000 (0.8% of the population). Protestants are about 1,678 persons (about 0.25% of the population). The constitution guarantees religious liberty.
A small number of Indians in Comoros are Hindu. Hinduism in both the independent Comoros and Mayotte plays a very small part in the islands' cultures, which are based on Islamic principles and local customs. However, Indian Hindus have contributed to the economy of the islands, most of them working as jewelers.
