Proclaim, “O mankind, I am for you only a clear Herald of Warning.” 49 "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. 50 And those who endeavour in respect of Our signs to frustrate them - those shall be the fellows of Flaming Fire. 51 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: 52 He would make Satan's temptations a trial for those whose hearts are hard and sick. The wrong-doers are far away from the Lord, 53 And so those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is Allah the Guide of those who have believed to a straight path. 54 And those who disbelieve will not cease to be in doubt thereof until the Hour cometh upon them on a sudden, or there cometh upon them the torment of a Barren Day. 55 The Kingdom upon that Day shall belong to Allah. He will judge between them. Those who believe and do good works shall be in Gardens of Bliss, 56 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
