Say, "O people, I am only to you a clear warner." 49 "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. 50 And those who strive in Our signs with the intention of disputing, are the people of 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 (This He permits) in order that He makes satan's interjections a temptation for those in whose hearts is a sickness and those whose hearts are hardened and the harmdoers are in a wide schism, 53 so that those who have received knowledge would know and believe that whatever happens with the Prophets and Messengers is the Truth from their Lord and will believe it. This will cause their hearts to become filled with awe. God guides the believers to the 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 The kingdom on that day shall be Allah's; He will judge between them; so those who believe and do good will be in gardens of bliss. 56 but those who deny the truth and deny Our signs will receive a humiliating punishment. 57
