What is Iman ?

Belief - îmân:

2.1 ) Iman (faith / belief) is of two kinds:
- The simple expression of faith in the teachings of the Quran and ahadith (or traditions);
- The formal declaration of belief in the six articles of Muslim creed:

1. in Allah
2. the Angels of Allah
3. the holy books of Allah
4. the Prophets of Allah
5. the Day of Judgement
6. Predestination to good and evil

In the traditions, iman includes practice (`amal), and all that belongs to the religious life of the Muslim. DI 204ii 2.2 ) Belief
The Muslim believes in One God, who is all-powerful and has no partner; believes in his messengers, sent to mankind for their guidance from the beginning of time; believes that Muhammad closed the cycle of messengers and that there can be no further revelation of the divine Law after him; believes that the Quran is the Word of God, unaltered and unalterable, and believes in the obligation to conform to the 'Five Pillars', which are the confession of faith, the five daily prayers, payment of the poor-due, the fast of Ramadan, and performance of the Pilgrimage to Mecca by those physically and financially able to undertake it. A Muslim may neglect one or more of the pillars (except the first) and still be counted as a believer, but if he denies their necessity he has placed himself outside the community. IDM3u

2.3 ) Ali (ra) was asked concerning belief îmân and he said:

"al-îmân ma`rifatun bil-qalb,
wa iqrâr bi-lisân wa `amal bi-l arkân"

"Belief îmân is appreciation / gnosis by the heart,
acknowledgement iqrâr with tongue and action `amalun with limbs."
