 The first necessity for progression along the path of spiritual development is MAN (faith). The mind and heart of a man should always be aware: Allah alone is His Master, Sovereign and Deity; seeking His pleasure is the aim of all his endeavors; and His commands alone are the commands that are to be obeyed. This should be a firm conviction, based not merely on the intellect, but also on acceptance by the will. The stronger and deeper this conviction, the more profound a man’s faith will be 

 What do Muslims believe?

Muslims have six major beliefs:

• Belief in one God (Allah)
• Belief in the Angels
• Belief in the holy books sent to all the prophets including Torah that was revealed to the prophet Moses, Bible that was revealed to the prophet Jesus, and Qur'an (Koran) that was revealed to the prophet Muhammad
• Belief in all the prophets sent by God including Noah, Abraham, Ishmael, Isaac, Jacob, Moses, Jesus and Muhammad. Although Muslims believe in Isa or Jesus they don't think of Jesus as the Son of God the way Christians do.
• Belief in the Day of Judgment and life after death. The best reward for performing good deeds is getting closer to God.
• Belief in divine decree. This means that God is all-powerful and nothing can happen without His permission, however, he has given human beings freedom to choose whether to be good or bad. In the end, everyone will be questioned about how they lived in this life.
