The Qur’an is the literal word of God, The Almighty (Allah in Arabic), revealed to Prophet Muhammad (peace be upon him) through the Angel Gabriel.
“The revelation of The Book is from Allah, the Mighty, the Wise.” Qur’an 39:1
The Qur’an is “a guidance for mankind… and the distinction (between right and wrong).”
Qur’an 2:185
It provides direction to help mankind judge between right and wrong, without which, man would surely be in loss.
