The Qur'an is an Admonition, Cure, Mercy and Guidance

Allah confers a great favor on His creatures in what He has sent down of the Gracious Qur'an to His Noble Messenger (Sallallahu Alayhi wa Sallam). He said:

O mankind! There has come to you good advice from your Lord.  A warning and a shield from shameful deeds.

and a cure for that which is in your breasts,   A cure from suspicion and doubts. The Qur'an removes all the filth and Shirk from the hearts.

a guidance and a mercy The guidance and the mercy from Allah are attained through it. This is only for those who believe in it and have firm faith in what it contains. As Allah said:

And We send down of the Qur'an that which is a cure and a mercy to those who believe, and it increases the wrongdoers nothing but loss. (17:82)  and;

Say: "It is for those who believe,  a guide and a cure.''    (41: 44)
