CENTRAL ASPECTS OF ISLAM

Revelation

Islam is based on a belief in revealed truth. The revelations through Muhammad are not seen by Muslims as instituting a new faith. Muslims therefore affirm belief in the Torah of Moses and the Injil, or Gospel, of Jesus.
Muhammad is seen as the "seal" of the prophetic succession, bringing a revelation in the Arabic language which both called people back to the original teachings of the previous prophets and fulfilled them.
The core of Islam's revealed message is seen as "submission" to God. Islam has seven fundamental beliefs, as follows:
the oneness of God
the books revealed by God
the prophets
the angels
the Day of Judgement
life after death
the omnipotence of God
The Qur'an
