Say: 'O men, I am only for you a plain warner.' 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 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 So that He may make what the devil includes a trial for those in whose hearts is a disease, and those whose hearts are hardened; indeed the unjust are extremely quarrelsome. 53 and that they who have been given knowledge may know that it is the truth from thy Lord and believe in it, and so their hearts be humble unto Him; and assuredly God ever guides those who believe to a straight 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
