The term "infidel" is not specifically used in the Qur'an to refer to Christians or any particular group. Instead, the Qur'an addresses different religious communities, including Jews and Christians, often referring to them as "People of the Book" (Ahl al-Kitab). This term acknowledges their scriptures and holds a special status compared to other non-Muslim groups.
However, the Qur'an does contain verses that discuss disbelief (kufr) and the consequences of rejecting faith. Interpretations of these verses can vary widely, and the context in which they were revealed is significant. Many scholars emphasize the importance of understanding these verses within the broader message of the Qur'an, which promotes compassion, dialogue, and understanding among different faiths.
In summary, while the Qur'an speaks about issues of faith and disbelief, it does not explicitly label Christians as "infidels" in the way that term might suggest in a modern context. Interpretations can vary, and discussions around these terms can be complex.
