What is the Quran?

Muslims believe that the Quran is the very word of God Almighty: a complete record of the exact words revealed by God through the Archangel Gabriel to Prophet Muhammad ( may peace and blessings of Allah be upon him).
The Quran was memorized by Prophet Muhammad ( may peace and blessings of Allah be upon him) and his followers, dictated to his companions, and written down by scribes, who cross-checked it during the Prophet’s lifetime. Not one word of its 114 surahs (chapters) has been changed over the centuries. The Quran is in every detail the same unique and miraculous text that was revealed to Muhammad ( may peace and blessings of Allah be upon him) over fourteen centuries ago.
The Quran is the principle source of every Muslim’s faith and practice. It deals with all subjects that concern us as human beings, including wisdom, doctrine, worship and law; but its basic theme is the relationship between God and His creatures. At the same time, the Quran provides guidelines for a just society, proper human conduct and equitable economic principles.

“He (God) has sent down to you the Book (the Quran) with truth, confirming what was revealed before; And He sent down the Torah (of Moses) and the Gospel (of Jesus) before this as a guide in humankind; and He sent down the Criterion (the Quran).”
(Quran 3:3-4)

Note that the Quran was revealed to Muhammad ( may peace and blessings of Allah be upon him) in Arabic only and the Quran exists only in the Arabic. So, any Quranic translation ( English or any other language ) is not a Quran or a version of the Quran. It is only a translation of the meaning of the Quran.
