Islam addresses major worldview questions through its core beliefs. It teaches that Allah is the one supreme God who created the universe. Humans were given free will but must obey Islamic law and submit to Allah's will. The Quran is Allah's revelation, and Muhammad was his final prophet. Muslims strive to live righteously according to sharia law to earn paradise in the afterlife and avoid eternal punishment in hell. History is unfolding as Allah decrees to give people chances to submit to him.
