As a Muslim, one must believe in:
1) The existence of God/Allah and ONLY him as God.
2) The Books we have been given (Torah, Gospel and Qur’an)
3) The Prophets we have been sent (from Noah, to Moses, to Abraham, to Jesus, to Muhammad pbut)
4) The unseen (angels, devil, spirits, Heaven, Hell…)
6) Judgement Day
