People of the Book

Question: Some mujtahids are of the opinion that the People of the Book are najis, while

Ahl-e Kitab(Christians, Jews and Zoroastrians) are ritually pure, but non-Muslims(Infidels) who are not from the People of the Book, they are ritually impure.

There is no objection to associating with the People of the Book socially.  However, it is better to avoid them.

By the People of the Book is meant all those who profess a divine religion and consider themselves the followers of one of the prophets of Allah.
