Shiavault - a Vault of Shia Islamic Books What A Muslim Should Know and Believe Zaruriyat al-Deen Every matter which is accepted as part of Islam by most of the Sunni and Shi'a scholars is called Zaruri al-deen (Plural = Zaruriyat al-deen). It makes no difference whether that matter is proved by the Qur'an, hadith, ijma' (consensus) or rational proofs. Also it does not matter whether the subject concerns Usul al-deen or Furu al-deen or Islamic ethics and morality.
Zururiy al-madh-hab Zururiy al-madh-hab (Plural - Zaruriyat al-madh-hab): Every matter which is accepted as part of a madh-hab by most of the 'ulama of that madh-hab. For example, justice of God and infallibility of the twelve Imams are among the Zaruriyat al-madh-hab of the Shi'a Ithna 'ashari faith. Anyone who refutes, rejects or has doubt about any of the Zaruriyat al-deen, becomes kafir and unclean although he might be claiming to be a Muslim.
Likewise, anyone who refutes, rejects or has doubt about any of the Zaruriyat al-madh-had al-Shi'a, becomes Sunni, although he might be claiming to be a Shi'a or might be believing in the five Usul al-deen. If they die without repentance, then in the eyes of Allah, the Prophet and the Shi'as of Ahlul-bayt, the former is kafir and najis, and the latter a Sunni. The former is called murtadd (apostate) from Islam; and the latter a murtadd from Shi'a madh-hab.
As mentioned in a preceding chapter, a person who rejects a Zaruriy al-deen or Zaruriyat al-madh-had, becomes murtadd only if he knows that it is a Zaruriy-edeen or Zaruriyat al-madh-had, or if he is a man who cannot be oblivious of this fact - for example, if he is a learned man of religion or has lived in a place where religious discourses are often held.
If a man does not reject openly a Zaruriy al-deen or Zaruriy al-madh-hab, but his behavior shows that he does not believe in it (even if he does not disclose his disbelief because of fear), then he will be treated as a murtadd. For example if he, says insulting things about an Imam and yet professes to believe in him, or insults the Qur'an and yet says that it is incumbent to respect the Qur'an.
Here we mention some of the Zaruriyat al-deen which are accepted by both the Shi'as and the Sunnis to be an integral part of the Islam. God There is one God, Ever-living, All-powerful and Eternal. He is All-knowing, All-perceiving. He does whatever He does by His own will. He speaks and is Truthful.
