Say (O Muhammad): "O people! I have been sent to you only as a plain warner (before the Doom strikes you)." 49 And [know that] those who attain to faith and do righteous deeds shall be granted forgiveness of sins and a most excellent sustenance; 50 but those who strive to void Our verses, thinking they have escaped, shall be the people of Hell' 51 Never did We send a messenger or a prophet before thee, but, when he framed a desire, Satan threw some (vanity) into his desire: but Allah will cancel anything (vain) that Satan throws in, and Allah will confirm (and establish) His Signs: for Allah is full of Knowledge and Wisdom: 52 [That is] so He may make what Satan throws in a trial for those within whose hearts is disease and those hard of heart. And indeed, the wrongdoers are in extreme dissension. 53 (He also does this) in order that those endowed with knowledge may know that it is the Truth from your Lord and that they may have faith in it and their hearts may humble themselves before Him. Verily Allah always directs those that believe to the Right Way. 54 The unbelievers will not cease to be in doubt about it until the Hour suddenly comes upon them, or the chastisement of an ominous day overtakes them. 55 The kingdom on that day shall be Allah's; He will judge between them; so those who believe and do good will be in gardens of bliss. 56 but for those who disbelieved Our verses and belied there awaits a humbling punishment. 57
