Iman (إِيمَان ʾīmān, faith or belief) in Islamic theology denotes a believer's faith in the metaphysical aspects of Islam. Its most simple definition is the belief in the six articles of faith, known as arkān al-īmān.
Faith (iman) breaks down into six axioms:
1.Belief in the existence and oneness of God (Allah).
2.Belief in the existence of angels.
3.Belief in the existence of the books of which God is the author: the Quran (revealed to Muhammad), the Gospel (revealed to Jesus), the Torah (revealed to Moses), and Psalms (revealed to David).
4.Belief in the existence of all Prophets: Muhammad being the last of them, Jesus the penultimate, and others sent before them.
5.Belief in the existence of the Day of Judgment: in that day, humanity will be divided into two groups: that of paradise and that of hell. These groups are themselves composed of subgroups.
6.Belief in the existence of God's predestination, whether it involves good or bad.
