Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 The righteously striving believers will receive forgiveness and honorable sustenance. 50 whereas those who strive against Our messages, seeking to defeat their purpose - they are destined for the blazing fire. 51 We have sent no messenger or apostle before you with whose recitations Satan did not tamper. Yet God abrogates what Satan interpolates; then He confirms His revelations, for God is all-knowing and all-wise. 52 [That is] so He may make what Satan throws in a trial for those within whose hearts is disease and those hard of heart. And indeed, the wrongdoers are in extreme dissension. 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 And the disbelievers will always be in doubt of it, to the extent that the Last Day will suddenly come upon them, or will come upon them the punishment of a day the result of which is not at all good for them. 55 The Kingdom upon that Day shall belong to Allah. He will judge between them. Those who believe and do good works shall be in Gardens of Bliss, 56 And those who disbelieved and belied Our signs - then these! for them will be a torment ignominous. 57
