The Quran is God's final revelation to humankind. God revealed the Torah to Moses, the Psalms to David, the Gospel to Jesus, and finally the Quran to Muhammad. Peace be upon all of them. No other book will come from God to surpass his final revelation.
The Quran withstands the test of time and scrutiny. No one can dispute the truth of this book. It speaks about past history and turns out right. It speaks about the future in prophecies and it turns out right. It mentions details of physical phenomena which were not known to people at the time; yet later scientific discoveries confirm that the Quran was right all along. Every other book needs to be revised to accord with modern knowledge. The Quran alone is never contradicted by a modern discovery.
(5) Your Roadmap for Life and Afterlife:
The Quran is the best guidebook on how to structure your life. No other book presents such a comprehensive system involving all aspects of human life and endeavor. The Quran also points out the way to secure everlasting happiness in the afterlife. It is your roadmap showing how to get to paradise.
(6) God's Gift of Guidance:
God has not left you alone. You were made for a reason. God tells you why he made you, what he demands from you, and what he has in store for you. If you operate a machine contrary to it's manufacture specification you will ruin that machine. What about you? Do you have an owner's manual for you? The Quran is from your function for success lest you fail to function. It is a healing mercy from God. It satisfies the soul, and cleans the heart. It removes doubts and brings peace.
(7) Your Calling Card to Communicate with God:
Humans are social creatures. We love to communicate with other intelligent life. The Quran tells us how to communicate with the source of all intelligence and the source of all life- the One God. The Quran tells us who God is, by what name we should address God, and the way in which to communicate with God. Are these not seven sufficient reasons for reading the Quran?
