Exert of Surah Al-Hajj

Have they not travelled through the land, and have they hearts wherewith to understand and ears wherewith to hear? Verily, it is not the eyes that grow blind, but it is the hearts which are in the breasts that grow blind.

And they ask you to hasten on the torment! And Allah fails not His Promise. And verily, a day with your Lord is as a thousand years of what you reckon.

And many a township did I give respite while it was given to wrong-doing. Then (in the end) I seized it (with punishment). And to Me is the (final) return (of all).

Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 

So those who believe (in the Oneness of Allah Islamic Monotheism) and do righteous good deeds, for them is forgiveness and Rizqoon Kareem (generous provision, i.e. Paradise).

But those who strive against Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), to frustrate and obstruct them, they will be dwellers of the Hell-fire.

Never did We send a Messenger or a Prophet before you, but; when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise:

That He (Allah) may make what is thrown in by Shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimoon (polytheists and wrong-doers, etc.) are in an opposition far-off (from the truth against Allahs Messenger and the believers).

And that those who have been given knowledge may know that it (this Quran) is the truth from your Lord, and that they may believe therein, and their hearts may submit to it with humility. And verily, Allah is the Guide of those who believe, to the Straight Path.
