No one can be forced to accept Islam as there is no compulsion in the religion of Islam. The Qur’an and Sunnah are clear on the ruling to have good, fair and just relations with non-Muslims and that they cannot be attacked unless there is a war, enmity or threat from them against Muslims. Teachings of the Qur’an and Sunnah encourage Muslims to develop good relations with the Christians on bases of Da’wah and not on the bases of enmity. This is obvious from the fact that Qur’an asks us to have a meaningful dialogue with them, calls them with a respectable title and allows having close social relations with them. As for as theological criticism is concerned this is to save them in the life hereafter and not to show the enmity.
