A study of the Quran shows that it aims to produce a universal approach in human beings. The Quran (1:2) introduces God as the ‘Lord of the worlds’ and not just the Lord of the Muslims or the Arabs. You will find that the Quran defines God as “rabb al-alamin”, or the Lord of Mankind. This shows that the God of Islam is one God: all divinity is invested in His Being.

The basic message of the Quran is that God is one. When you read the Quran, you will find such statements repeatedly in the Quran: ‘O man, it is your Lord, who is addressing you. Listen to His words and follow Him.’ Even this style of address is quite exceptional. This kind of direct divine invocation leaves a lasting impression on man. He feels his Lord is directly addressing him. This feeling compels man to take the assertions of the Quran with extreme seriousness, rather than treat them like everyday statements in an ordinary book.

Islam is a universal religion. The Quran fosters a universal outlook among its followers. One who adopts the Quranic way will start thinking at the universal level. His personality will be linked simultaneously to the Creator of the World and with the entire human brotherhood. Despite being located in a particular region, he becomes a citizen of the universe as far as his thinking is concerned. In this respect, it can rightly be said that Islam or the Quran promotes universal citizenship.

The Quran is no new heavenly scripture. It is only an original edition of the previous heavenly scriptures. The Quran enshrines the same teachings as found in previously revealed scriptures. However, these ancient scriptures are no longer preserved in their original state. Later additions and deletions have rendered them unreliable, whereas the Quran, preserved in its original state, is reliable. When a believer in the previously revealed scripture turns to the Quran, it does not mean that he rejects his own belief but instead amounts to his having rediscovered his faith in an original form. In this way, the Quran is the Guidebook for all humanity.

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.
