Rules of non-Muslims According to the Grand Ayatollah Sayyid Ali Hosseini Khamenei
Grand Ayatollah Sayyid Ali Hosseini Khamenei:
Q 312: Some mujtahids are of the opinion that the People of the Book are najis, while some others consider them pure. What is your opinion?
A: It is not established that the People of the Book are najis themselves; rather, we consider them as pure by themselves.
Q 313: Are the People of the Book, who accept the Prophethood of the Seal of the Prophets (s.) but follow the practice of their ancestors in matters of worship, considered non- Muslims as far as of the rules of purity are concerned?
A: Solely having faith in the Prophethood of the Seal of the prophets (s.) is not sufficient for considering someone Muslim. However, such persons are considered pure if they belong to The People of the Book.
Q 315: What are the religions whose followers are considered the People of the Book? What is the criterion for defining the limits of social relations with them?
A: 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, the Glorious and the Exalted (may peace be upon our Prophet and his progeny and upon them) and who possess a heavenly scripture from those revealed to the Prophets (a.), such as the Jews, the Christians, the Zoroastrians and similarly the Sabeans who, on the basis of our research, are among the People of the Book. Therefore, the rule of the People of the Book applies to the followers of these religions, and there is no objection to associating with them socially, while observing Islamic laws and morals [1]
