Say (O Muhammad): "O people! I have been sent to you only as a plain warner (before the Doom strikes you)." 49 Then those who believe and work righteous works - for them is forgiveness and a provision honourable. 50 And those who strive against Our signs to void them -- they shall be the inhabitants of Hell. 51 Never have We sent a Messenger or a Prophet before you, but when he hoped, satan tampered with his hope. But Allah supersedes the tampering of satan and confirms His verses. And Allah is the Knower, the 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 [God renders Satan's aspersions null and void] so that they who are endowed with [innate] knowledge might know that this [divine writ] is the truth from thy Sustainer, and that they aught believe in it, and that their hearts might humbly submit unto Him. For, behold, God does guide onto a straight way those who have attained to faith 54 And the unbelievers will not cease to be in doubt of it, until the Hour comes on them suddenly, or there shall come upon them the chastisement of a barren day. 55 The Kingdom upon that day shall belong to God, and He shall judge between them. As for those who believe, and do deeds of righteousness, they shall be in Gardens of Bliss. 56 And (as for) those who disbelieve in and reject Our communications, these it is who shall have a disgraceful chastisement. 57
