There are six basic beliefs of faith in Islam, known as the Arkān al-Īmān, which form the basis of Muslim beliefs. They are derived from the Quran and the Hadith of Gabriel.
The six beliefs are as follows:
1- Belief in the Oneness of God (Allah): The existence of only one God, the creator, sustainer, and final ruler of the universe, without any partner or equal (Tawhid).
2- Belief in the Angels (Malaikah): The existence of angels, created from light by God, to carry out His commands.
3- Belief in the Books (Kutub): The existence of books revealed to His prophets, including the Quran revealed to Prophet Muhammad, the Torah revealed to Moses, the Gospel revealed to Jesus, the Psalms revealed to King David, and the Scrolls revealed to Abraham.
4- Belief in the Prophets and Messengers (Rusul): The sending of prophets to guide humankind, beginning with Adam and culminating with Muhammad.
5- Belief in the Day of Judgment (Akhirah): The end of the world, resurrection, and accountability of all actions, resulting in eternal bliss or hell.
6- Belief in the Divine Decree (Qadar): The supreme knowledge and control of everything by God, without anything happening without His will and consent.
