Like all previous scriptures, the Quran delivers the one and only message of God to mankind, worship God alone and follow God alone.
God describes the Quran as a beacon to guide, warn, and bring good news. It is also a statute book with set laws and systems for mankind.
[16:102] Say, "The Holy Spirit has brought it down from your Lord, truthfully, to assure those who believe, and to provide a beacon and good news for the submitters."
[2:185] Ramadan is the month during which the Quran was revealed, providing guidance for the people, clear teachings, and the statute book. ...
[13:37] We revealed these laws in Arabic, and if you ever acquiesce to their wishes, after this knowledge has come to you, you will have no ally, nor a protector, against God.
It’s a book of wisdom, and healing for anything that troubles our hearts.
[10:57] O people, enlightenment has come to you herein from your Lord, and healing for anything that troubles your hearts, and guidance, and mercy for the believers.
It sets every kind of example for us to heed the guidance, learn and lead a righteous life. So this means that this book, Quran, is a roadmap for our salvation.
[39:27] We have cited for the people every kind of example in this Quran, that they may take heed.
[6:51] And preach with this (Quran) to those who reverence the summoning before their Lord - they have none beside Him as a Lord and Master, nor an intercessor - that they may attain salvation.
Quran clearly explains what it takes to be on the straight path and what would be the consequences of adopting the crooked path, it’s entirely up to us to choose.
[76:3] We showed him the two paths, then he is either appreciative, or unappreciative.
[41:46] Whoever works righteousness does so for his own good, and whoever works evil does so to his own detriment. Your Lord is never unjust towards the people.
