SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 And those who have believed and done righteous deeds - for them is forgiveness and noble provision. 50 But the ones who strove against Our verses, [seeking] to cause failure - those are the companions of Hellfire. 51 Never did We send a Messenger or a Prophet before you (O Muhammad), but that whenever he had a desire, Satan interfered with that desire. Allah eradicates the interference of Satan and strengthens His Signs. Allah is All-Knowing, All-Wise. 52 So that He may make what the Shaitan casts a trial for those in whose hearts is disease and those whose hearts are hard; and most surely the unjust are in a great opposition, 53 At the same time those who have been given knowledge may know that this is the truth from your Lord, and come to believe in it, and their hearts become submissive to Him. Verily God guides those who believe, to the even 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 On that Day all sovereignty shall be Allah's and He will judge among them. Then those who believed and acted righteously shall be in Gardens of Bliss. 56 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
