Say thou: mankind! I am unto you only a warner manifest. 49 For those who believe and do the right is forgiveness and gracious provision. 50 whereas those who strive against Our messages, seeking to defeat their purpose - they are destined for the blazing fire. 51 We have sent no messenger or apostle before you with whose recitations Satan did not tamper. Yet God abrogates what Satan interpolates; then He confirms His revelations, for God is all-knowing and all-wise. 52 He makes Satan's suggestions a trial for those whose hearts are diseased or hardened, and, surely, the wrongdoers are far gone in error, 53 And that those who have been given knowledge may know that it is the truth from thy Lord, so that they may believe therein and their hearts may submit humbly unto Him. Lo! Allah verily is guiding those who believe unto a right path. 54 whereas those who are bent on denying the truth will not cease to be in doubt about Him until the Last Hour comes suddenly upon them and [supreme] suffering befalls them on a Day void of all hope. 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 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
