SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 And (as for) those who strive to oppose Our communications, they shall be the inmates of the flaming fire. 51 Whenever We sent any messenger or prophet before you, and he recited anything [of Our revelation], Satan tampered with it. But God abrogates Satan's interjections and then He firmly reaffirms His revelations. God is all knowing and all wise. 52 He would make Satan's temptations a trial for those whose hearts are hard and sick. The wrong-doers are far away from the Lord, 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 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 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 for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
