Say: O mankind! I am only a plain warner unto you. 49 "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. 50 And (as for) those who strive to oppose Our communications, they shall be the inmates of the flaming fire. 51 And We did not send before you any apostle or prophet, but when he desired, the Shaitan made a suggestion respecting his desire; but Allah annuls that which the Shaitan casts, then does Allah establish His communications, and Allah is Knowing, 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 infidels will remain in doubt about it till the Hour overtakes them unawares, or the punishment of the barren day destructive should come upon them. 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 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
