As muslims who surrender completely to Allah (SWT) the creator of the Heavens and the earth, we are required to believe in six things to complete our Iman:
a. Allah is maker of everything, owner/master of everything in this universe.
b. Worship is only for Allah. No one or nothing else is worthy of worship.
c. Names & Attributes of Allah
The Taurah, The Gospel, The Quran etc
4. Messengers and Prophets
5. Last day or the Day of Judgement
6. Qadr(Divine Decree) – the Good and Bad of it.
