Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 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 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 That He (Allah) may make what is thrown in by Shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimun (polytheists and wrong-doers, etc.) are in an opposition far-off (from the truth against Allah's Messenger and the believers). 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 And those who disbelieve shall not cease to be in doubt concerning it until the hour overtakes them suddenly, or there comes on them the chastisement of a destructive day. 55 [All] sovereignty that Day is for Allah; He will judge between them. So they who believed and did righteous deeds will be in the Gardens of Pleasure. 56 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
