The Quran is the preserved version of God’s guidebook revealed to Prophet Muhammad, the last prophet, over a period of 23 years from 610 till 632 AD. As the Word of God, the Lord of all humanity, the Quran is a guidebook for all humanity. The main themes of the Quran are enlightenment, closeness to God, peace, and spirituality. The message of the Quran, in a nutshell, is the belief in One God considering oneself answerable to Him, and a firm belief that the guidance sent by God through Prophet Muhammad is the truth and leads to man’s salvation.

When you read the Quran, you will repeatedly find it stated that it is the Word of God.  A unique feature of the Quran is that it does not have any inconsistency: “Do they not ponder over the Quran? If it had not come from God, they would have found in it many contradictions (ikhtilaf).” (4:82)

A Book with such a rare quality can only be from God and God alone. Only God’s Word will remain perennially free of all inconsistency. The work of anyone other than God will be always marred by imperfection. This shows that the Quran is the Word of God.
