SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto 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 against Our Signs, to frustrate them,- they will be Companions of the Fire." 51 Never did We send a Messenger or a Prophet before you (O Muhammad), but that whenever he had a desire, Satan interfered with that desire. Allah eradicates the interference of Satan and strengthens His Signs. Allah is All-Knowing, All-Wise. 52 (He does this) in order that He may make the evil caused by Satan a trial for those in whose hearts there is sickness (of hypocrisy), whose hearts are hard (and vitiated). Surely these wrong-doers have gone too far in their dissension. 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 it is God who will be the Absolute King and Judge of (mankind). The righteously striving believers will go to Paradise 56 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
