In the Name of Allah,Most Gracious,Most Merciful

Ibn Umar(RA) relates that the Holy Prophet (SAW) said:"Islam is based on five articles:

1. To bear witness that there is none worthy of worship save Allah and that Muhammad (PBUH) is the Messenger of Allah
2. To observe Prayer (Salat)
3. To Pay Zakat (Alms giving)
4. To Fast in the month of Holy Ramzan
5. To perform the Pilgrimage to the House of Allah (Hajj)

There are six articles of Islamic faith:

1. Belief in ALLAH
2. Belief in Angels,
3. Belief in the Books (Scriptures) of ALLAH,
4. Belief in the Prophets of ALLAH,
5. Belief in the Day of Judgment and
6. Belief in the Divine Laws

Umar ibn Khattab (RA) relates: We were sitting in the company of the Holy Prophet (SAW) when suddenly a man arrived. He was wearing clean, white clothes and his hair was jet black. He did not look as though he was a traveler and he was not known to any of us. He sat down close to the Holy Prophet (SAW), his knees touching the knees of the Holy Prophet (SAW),
he said:"O Muhammad,tell me something about faith."
The Holy Prophet,(SAW) be upon him,replied:
"Faith is that you should believe in Allah, His Angels, His Books and His Prophets; that you should believe in the Day of Judgment and that you should believe in the Divine Laws relating to good and evil." (Tirmidhi)

Ali ibn Talib (RA) relates that he Holy Prophet (SAW) said: �The faith is that one recognizes God at heart, accepts Him verbally and acts on His commandments."(Ibne Majah)

Allah (SWT)SAYS in QURAN:{Invite (mankind, O Muhammad) to the Way of your Lord (i.e. Islam) with wisdom (i.e. with the Divine Inspiration and the Qur'an) and fair preaching, and argue with them in a way that is better.Truly, your Lord knows best who has gone astray from His Path, and He is the Best Aware of those who are guided.} (Holy Quran-16:125)
