basic beliefs of muslims

Belief in God:
Muslims believe in one, incomparable God, He has no son nor partner, and that one has the right to be worshipped but Him alone. He is the true God, and every other god is false. In the Qur'an, God describes Himself:
Say, “He is God, the One. God, to Whom the creatures turn for their needs. He begets not, nor was He begotten, and there is none like Him.” (Qur'an, 112:1- 4)

Belief in the Angels:
Muslims believe in the existence of the angels and that they are honoured creatures. The angels worship God alone, obey Him, and act only by His command. Among the angels is Gabriel, who brought down the Qur'an to Muhammad.

Belief in God’s Revealed Books:
Muslims believe that God revealed books to His messengers as proof for mankind and as guidance for them. Among these books is the Qur'an, which God revealed to the Prophet Muhammad . God has guaranteed the Qur'an’s protection from any change.

Belief in the Prophets:
Muslims believe in the prophets and messengers of God, starting with Adam, including Noah, Abraham, Ishmael, Isaac, Jacob, Moses, and Jesus (peace be upon them). But God’s final message to man, a repeating of the eternal message, was revealed to the Prophet Muhammad. Muslims believe that all the prophets and messengers were created human beings who had none of the divine qualities of God.

Belief in the Day of Judgment:
Muslims believe in the Day of Judgment (the Day of Resurrection) when all people will be resurrected for God’s judgment according to their beliefs and deeds.

Belief in Al-Qadar:
Muslims believe in Al-Qadar, which is Divine Predestination, but this belief in Divine Predestination does not mean that human beings do not have freewill. Rather, Muslims believe that God has given human beings freewill. This means that they can choose right or wrong and that they are responsible for their choices. The belief in Divine Predestination includes belief in four things
: 1) God knows everything. He knows what has happened and what will happen.
2) God has recorded all that has happened and all that will happen.
3) Whatever God wills to happen happens, and whatever He wills not to happen does not happen.
4) God is the Creator of everything.
