Those who follow the Messenger, the unlettered Prophet, whom They find mentioned In their own (scriptures), - In the Torah and the Gospel;- for He commands them what is just and forbids them what is evil; He allows them As lawful what is good (and pure) and prohibits them from what is bad (and impure); He releases them from their heavy burdens and from the yokes that are upon them. So it is those who believe In him, honor him, help him, and follow the light which is sent down with him,- it is They who will prosper." (The Holy Quran: 7: 157)

The Quran was revealed to the Prophet (SAW) in which Allah commanded him to obey everything that was ordered of him; that is, to convey and explain His message to the people.
