The Quran
The Quran is the Muslim scripture, that is to say the scripture of the followers of Islam. Islam is the religion established among the Arabs – a people until then largely confined to the ArabianPeninsula – by the Prophet Muhammad in the early seventh century. The Quran was revealed to Prophet Muhammad by God through the agency of the angel Gabriel; this took place partly in Mecca, his hometown, and partly in Medina, where he succeeded in creating a state in an otherwise stateless tribal society. The message was revealed in Arabic, the language of the people it was initially addressed to, even though the message was ultimately for the whole of humanity.
Qurʾān , or Koran, Sacred scripture of Islam, regarded by Muslims as the infallible word of God, revealed to the Prophet Muhammad. The book, first compiled in its authoritative form in the 7th century, consists of 114 chapters (sūrahs) of varying length, written in Arabic. The earliest sūrahs call for moral and religious obedience in light of the coming Day of Judgment; the ones written later provide directives for the creation of a social structure that will support the moral life called for by God. The Qurʾān also provides detailed accounts of the joys of paradise and the terrors of hell. Muslims believe that the God who spoke to Muhammad is the God worshiped by Jews and Christians but that the revelations received by those religions are incomplete. Emphasis on the stern justice of God is tempered by frequent references to his mercy and compassion. The Qurʾān demands absolute submission (islam) to God and his word, and it serves as the primary source of Islamic law. It is regarded as immutable in both form and content; traditionally translation was forbidden. The translations available today are regarded as paraphrases to facilitate understanding of the actual scripture.
The Quran’s Core Message
In essence, the message of the Quran is to bring to our attention that we were not created in vain, and that we will be held responsible for our conduct on this earth. In the Quran, God indicates that He created the human to be His trustee on earth. This is actually an honor given by God to the human being, dignity to be the trustee of God even though He doesn’t need our worship and our obedience. It is for our own benefit.
The message of the Quran is to say or believe that guidance that is coming from the Creator of the universe is the ultimate guidance, for God has the ultimate wisdom, power, and knowledge. And God alone is the ultimate authority and should be obeyed without qualification, obedience that is based not just on fear or reward but on the love of God.
It indicates again that one should look forward, like you mentioned for example in terms of daily life, one should look after the Quran for guidance. The Quran generally gives broader guidance in most aspects within concepts, and there are some details there, but normally to the broader guidance so as to conduct our lives according to the will of God. And the Quran finally indicates that since a human being is a free agent, he or she can choose to obey God or disobey, to believe or reject faith.
Then that kind of privilege has a responsibility that goes with it because ultimately we have a responsibility to return back to God. There will be resurrection. There will be life after death in which people would be rewarded, or otherwise, according to their conduct.
So that in a way can be put as a capsule or a capsulized nature or summary on the Quran, because it is in my humble belief as a Muslim that all prophets of God have taught this exact same core message as the Quran taught.
