Without doubt, to know the cause of a thing, the occasion on which an incident has come in a particular way, and the circumstances under which an event has taken place in a certain manner can remove a great deal of ambiguity because of which it is not only difficult to understand this thing, but also it is possible to understand it quite differently from what it really is.

From this point of view we can perceive the importance of knowing the causes of the revelation of the Qur'anic verses, the occasion on which each one was sent to The Messenger of Allah [peace be upon him], the context in which it should be placed, and the event or incident it was intended to serve.

In this connection, we are pleased to introduce to the reader on of the most important and the most advantageous books in this field. «Kitab Lubab al-Nuqul fi Asbab Al-Nuzul» written by Abd al-Rahman Ibn Abu Bakr Jalal al-Din al-Suyuti (849-911 AH/1445-1505 AD).

We hope this book will be of benefit to the reader and an addition to our good deeds in the world and in the hereafter.
