The Qur'an is the final Message from Allah to humanity. It was transmitted to us in a chain starting from the Almighty Himself through the angel Jibreel (Gabriel) to the Prophet, Muhammad (peace be upon him). This message was given to the Prophet (peace be upon him) in parts over a period spanning approximately 23 years, from when the Prophet was 40 till the time of his demise (610 CE to 633 CE). The language of The Message is Arabic, from which it has been translated into many other languages.
The Qur'an is the Divine book for the Muslims and its authority is unchallengeable. For the basis of Islam, it constitutes the foundation, as it is the direct word of Allah, the remaining building of which is the Sunnah (the example) of the Prophet (peace be upon him), which although from the Prophet, is what Allah has preferred for the Muslims.
The unchallengeable authority of the Qur´an is due to it being unchanged and remaining its original form, which is unique in all the divine books.
See for yourselves the beauty of the Qur´an by reading it, listening to it and pondering over its meaning.
It must be emphasized that the translations presented will always have a degree of interpretation added to them. These interpretations more often than not are correct, but at times can confuse those who wish to read the literal meaning.
