SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 For those who believe and do the right is forgiveness and gracious provision. 50 Those who try to challenge Our miracles will be the dwellers of hell." 51 Satan would try to tamper with the desires of every Prophet or Messenger whom We sent. Then God would remove Satan's temptations and strengthen His revelations. God is All-knowing and All-wise. 52 He makes Satan's suggestions a trial for those whose hearts are diseased or hardened, and, surely, the wrongdoers are far gone in error, 53 so that those who are given knowledge may realize that this is the truth from your Lord and thus believe in it, and so that in their hearts they may humbly submit to Him. God will surely guide the faithful to a straight path. 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 those who disbelieved and belied Our Verses (of this Quran), for them will be a humiliating torment (in Hell). 57
