The Quran, the last revealed word of Allah and it is for whole humanity and was revealed to the Last Prophet, Muhammad صلى الله عليه وسلم in the language of arabic, through the angel Jibraa’il over a period of 23 years. The Quran was revealed in verbal form to the Prophet صلى الله عليه وسلم, and was later compiled into the form of a complete book during the rule of Hazrat Abu Bakr Siddiq رضى الله تعالى عنه though even before this it was memorised by thousands of companions and was recited in the presence of the Prophet صلى الله عليه وسلم.
It deals with all the subjects which concern human beings: wisdom, doctrine, worship, transactions, law, etc., but its basic theme is the relationship between almighty Allah and His creatures. At the same time, it provides guidelines and detailed teachings for a just society, proper human conduct, and an equitable economic system.
The Quran represents the fountainhead of Divine guidance for every humanity. Its revelation to the Prophet Muhammad (peace be upon him) and his practical implementation of the revelation, completed Allah’s blessing for humanity, in providing us with a belief and value system that is valid for all times.
The Quran confirms the revelations given to earlier Prophets, though these might not be accessible to us, in the form they were originally revealed. The most sublime language and a rational message that directly appeals to the human heart have caused this Divine book to move nations and civilizations. It will continue to guide those who turn to God with a sincere heart, for all times.
Note that the Quran was revealed to Muhammad in Arabic only. So, any Quranic translation, either in English or any other language, is neither a Quran, nor a version of the Quran, but rather it is only a translation of the meaning of the Quran. The Quran exists only in the Arabic in which it was revealed.
