Muslims are encouraged to engage in respectful dialogue with People of the Book and those of other religions. “And do not dispute with the People of the Book, except in ways that are best” (Qur'an 29:46). Muslims generally try to avoid heated arguments or endless debate about matters of faith.
Muslims are also encouraged to invite others to the faith, but do not have organized missionary programs. The Arabic word for inviting others to Islam is da'wah, which means “calling others to faith.” Muslims are instructed to use good manners when talking with others about their faith. “Invite to the Way of thy Lord with wisdom and beautiful preaching, and discuss with them in ways that are best and most gracious. For thy Lord knows best who have strayed from His path, and who receive guidance” (Qur'an 16:125).
Most Muslims are happy to answer questions about their faith, as long as the questioner has a genuine desire to learn and not ridicule. Certainly, mutual dialogue and respectful discussion is the best way to learn about another people so that we can build bridges and create a more civilized and peaceful community. Ignorance breeds prejudice, which only leads to more hatred and conflict.
