In the Qur’an, Allah tells us that talking with others about religion is one of the most important acts of worship that believers can perform. This worship encompasses ever aspect of life. In their words, demeanor, and attitudes, believers are responsible every moment for telling others about the good moral life and for representing of Islam. Their conversations among themselves are actually mutual communications of religion. They call upon each other to follow the Qur’an’s commands and to show its morality in their lives. In short, communicating religion is part of each believer’s identity. On the other hand, as the Qur’an tells us, arguing belongs to the unbelievers’ general make-up. Therefore, believers must always be careful of how they spread religion so that such efforts do not tend toward argument. Arguing has no place in the Qur’anic morality. In this book, we will examine with detailed reference to the Qur’an the methods and rationale that believers should use when communicating religion to others and see the satanic nature of arguing.
