Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 whereas those who strive against Our Signs, seeking to profane them, they are the friends 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 And those who disbelieve will not cease to be in doubt thereof until the Hour cometh upon them on a sudden, or there cometh upon them the torment of a Barren Day. 55 The Sovereignty on that day will be Allah's, He will judge between them. Then those who believed and did good works will be in Gardens of Delight, 56 And those who disbelieved and denied Our signs – for them will be a disgraceful punishment. 57
