Islam was spread by word of mouth. Also many of the Imams(leaders) sent out people to spread the word in different regions of the world. Islam in India had a negative effect as it caused many disputes between the Muslims and the Hindus. A nation was divided. But thankfully now they live in harmony in most parts.
Islam spread to India through trade, military conquests, and Sufi missionaries by the 7th century. The impact included a rich cultural exchange, social changes, and some religious conflicts. Today, many regions experience harmony between Hindu and Muslim communities despite their complex history.
