Tell them: "O men, it's my duty to warn you clearly." 49 The righteously striving believers will receive forgiveness and honorable sustenance. 50 And those who endeavour in respect of Our signs to frustrate them - those shall be the fellows of Flaming 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 He (Allah) may make what is thrown in by Shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimun (polytheists and wrong-doers, etc.) are in an opposition far-off (from the truth against Allah's Messenger and the believers). 53 and so that those to whom knowledge has been given will know that this is the truth from your Lord and so believe in it and that their hearts will be humble to Him. Indeed, Allah will surely guide those who believe to a Straight Path. 54 The unbelievers will never cease to doubt it until the Hour overtakes them suddenly or the punishment of the Barren Day comes upon them. 55 The sovereignty on that Day will be that of Allah (the one Who has no partners). He will judge between them. So those who believed (in the Oneness of Allah Islamic Monotheism) and did righteous good deeds will be in Gardens of delight (Paradise). 56 but those who deny the truth and deny Our signs will receive a humiliating punishment. 57
