Urdu is a language historically associated with the Muslims of the Indian subcontinent. It is the national language of Pakistan, and an official language of six Indian states. Apart from specialized vocabulary, Urdu is mutually intelligible with Hindi, which is associated with the Hindu community. Hindi-Urdu is the fourth most commonly spoken language in the world, after Mandarin, English, and Spanish. Because of the difficulty in distinguishing between Urdu and Hindi speakers in India and Pakistan, as well as estimating the number of people for whom Urdu is a second language, the estimated number of speakers is uncertain and controversial.
Urdu is an important language in the Ahmadiyya Muslim Community, because it's founder, Hazrat Mirza Ghulam Ahmad, and the caliphs who have succeeded him have written numerous books and delivered numerous speeches in Urdu.
