It is my understanding that a Muslim must believe in the articles of faith, follow the commandments in the Quran and use the historical accounts of previous nations for guidance and learning.
1- God. God is One. He is the Supreme and Eternal, the Creator and Provider, the Merciful and Compassionate. God has no family. God has no equal. He is invisible to the human eye. He is not made of any matter, He is timeless, and He is the God of everything in the Universe. God asks us to know Him, to love Him, and to follow His laws for our benefit and salvation.
2- Angels. Angels are spiritually obedient forces created by God to fulfill His commands and worship Him tirelessly.
3- The Divine Revelations (Books). Belief in the revelations sent by Almighty God to His prophets and messengers including the Quran, the Torah, the Gospel, the Scrolls of Abraham and the Psalms of David. One cannot be a Muslim without the belief that Mohammad was his last prophet. Without believing (obeying) the commandments of Allah, one cannot attain salvation.
4- Prophets. All of the messengers and prophets of God such as Noah, Moses, Solomon, Jesus and Muhammad were mortal human beings. They were endowed with Divine Revelations and appointed by God to teach humankind how to submit to His will and obey His laws.
5- Resurrection after Death and the Day of Judgment. Belief in the end of the world and an appointed day of resurrection to face the Judgment of Almighty God. Also, belief in heaven and hell for reward and punishment is a part of this article of faith.
6- Preordainment (Qadar) God has the eternal knowledge and ultimate control over everything that He has created.
7- Commandments. Believe and follow the commandments of Allah as they are in the Holy Quran. (Ehkamaat)
8- Similes and metaphors. The Quran contains illustrious examples of historical and future events to show how Allah works. (Mutashabihaat).
These historical accounts do not make into the articles of faith and whether one believes in them verbatim or not, does not destroy the faith. The stories of Ashab-e-Kahf, Khizr and Moses, the overnight journey of the Holy Prophet from Mecca to Medina (Ma’araj), Virgin birth of Jesus and his ascension to heavens are just a few controversial examples because their verbatim translations seem to defy common sense.
