Say thou: mankind! I am unto you only a warner manifest. 49 So those who believe and act righteously shall be granted forgiveness and an honourable sustenance, 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 This is in order to make the interpolations of Satan a test for those whose hearts are diseased and hardened: Surely the sinners have gone far in dissent. 53 And that those who have been vouchsafed knowledge may know that it is the truth from thy Lord and may believe therein, and so their hearts may submit thereto. And verily Allah is the Guide of those who believe unto a path straight. 54 The unbelievers will never cease to doubt it until the Hour overtakes them suddenly or the punishment of the Barren Day comes upon them. 55 The sovereignty on that Day will be that of Allah (the one Who has no partners). He will judge between them. So those who believed (in the Oneness of Allah Islamic Monotheism) and did righteous good deeds will be in Gardens of delight (Paradise). 56 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
