The Qur'an contains revelation from Allah and the true nature of revelation is to guide mankind from darkness to light:

'A book which we have revealed unto thee in order that thou mightest lead mankind out of the depths of darkness into light- by the leave of thy Lord- to the way of (Him) the exalted in power, worthy of all praise' (Al-Qur'an 14: 1).

The revelation came in the language of the messenger and his people in order that it might be understood:

'We have made it a Qur'an in Arabic that ye may be able to understand (and learn wisdom)' (Al-Qur'an 43: 3).

In the nrocess of understanding a message two steps are essential:

• To receive the message correctly and completely, in this case to receive its words correctly and completely.
• To 'decode' it, to grasp the meanings of the message received.
