SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 So those who believe (in the Oneness of Allah Islamic Monotheism) and do righteous good deeds, for them is forgiveness and Rizqun Karim (generous provision, i.e. Paradise). 50 And those who endeavour in respect of Our signs to frustrate them - those shall be the fellows of 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 And so that the people given the knowledge may know that it is the truth from your Lord, in order that they may accept faith in it, therefore their hearts may humble before Him; and indeed Allah will guide the believers on the Straight Path. 54 The unbelievers will continue to doubt the Quran until the Hour of Doom suddenly sizes them or the torment of the last day strikes them. 55 The dominion on that Day will be Allah's; He shall judge between them; then those who believed and worked righteous works shall be in the Gardens of Delight. 56 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
