The Individual and Collective Benefits of Correctly Believing "The Qur`an is the Speech of Allaah, Not Created!" and The Individual and Collective Consequences of Disbelieving

Bismillaah Al-Hamdulillaah wa salatu wa salaamu 'ala rasulullaah 

Amma-ba'd

The Qur`an is The Speech of Allaah - not created - and Perfect in its words and meanings

Shaikh al-'Uthaimeen (rahimahullaah) said in his sharh of al-'Aqeedah al-Wasitiyyah: 

[Allaah said:] And this is a blessed Book (the Qur`an) which We have sent down, so follow it and fear Allaah (i.e. do not disobey His Orders), that you may receive mercy (i.e. saved from the torment of Hell). (Al-An'aam, ayah 155)

...It (the Qur`an) is blessed for its marvelous effects. The Muslims have striven against the lands of the kufaar with it, for Allaah says:

...But strive against them with the utmost endeavor, with it. (Al-Furqan, ayah 52) ----> (meaning with the Qur`an).

The Muslims were victorious in the Eastern and the Western lands with this Qur`an, such that they gained authority over them. If we return to it, we shall gain authority over the East and the West of the world, as was done by our Salaf. We beseech Allaah for that.

Shaikh al-'Uthaimeen (rahimahullaah) also said:

We learn that if we believe that The Lord of all that exists did speak the Qur`an, then that will cause us to revere the Qur`an, and believe in its sanctity, implement the commands it came with, and abstain from the prohibitions and warnings that are contained in it, and trust whatever information that comes in it about Allaah Tabarak wa ta'aala, and His creatures of the past and what is to come.
