Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 Then those who believe and work righteous works - for them is forgiveness and a provision honourable. 50 But those who strive against Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), to frustrate and obstruct them, they will be dwellers of the Hell-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 makes Satan's suggestions a trial for those whose hearts are diseased or hardened, and, surely, the wrongdoers are far gone in error, 53 And that those who have been given knowledge may know that it is the truth from thy Lord, so that they may believe therein and their hearts may submit humbly unto Him. Lo! Allah verily is guiding those who believe unto a right 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 On that Day, all dominion shall [visibly] belong to God, He shall judge [all men and make a distinction] between them: thus, all who had attained to faith and did righteous deeds shall find themselves in gardens of bliss, 56 And those who disbelieved and belied Our signs - then these! for them will be a torment ignominous. 57
