Say: O people! I am only a plain warner to you. 49 Then (as for) those who believe and do good, they shall have forgiveness and an honorable sustenance. 50 whereas those who strive against Our messages, seeking to defeat their purpose - they are destined for the blazing fire. 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 [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 on whom knowledge has been bestowed may learn that the (Qur'an) is the Truth from thy Lord, and that they may believe therein, and their hearts may be made humbly (open) to it: for verily Allah is the Guide of those who believe, to the Straight Way. 54 And those who disbelieve will not cease to be in doubt thereof until the Hour come upon them unawares, or there come unto them the doom of a disastrous day. 55 On that Day all sovereignty shall be Allah's and He will judge among them. Then those who believed and acted righteously shall be in Gardens of Bliss. 56 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
