The Quran distinguishes between Jews and Christians, calling them 'People of the Book' and not classifying them as 'mushrikeen' or those who associate partners with Allah.

The Quran explicitly condemns 'shirk', which is the act of associating partners with Allah. This is evident in verses such as Surah 4:48 and 4:116, which emphasize that Allah does not forgive those who ascribe partners to Him. The traditional Christian understanding of the Trinity, which posits that Jesus is divine, directly conflicts with the Islamic view of monotheism. Therefore, Christians can be seen as 'mushrikeen' based on their beliefs. Furthermore, the argument that the Quran differentiates Jews and Christians from 'mushrikeen' is based on selective interpretations of verses like Surah 98:1 and Surah 29:46, which do not negate the reality of 'shirk' but rather highlight the potential for dialogue and common ground. Ultimately, the classification of Jews and Christians as 'People of the Book' does not exempt them from the implications of 'shirk' as understood in traditional Islamic theology.
