Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 But the ones who strove against Our verses, [seeking] to cause failure - those are the companions of Hellfire. 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 He would make Satan's temptations a trial for those whose hearts are hard and sick. The wrong-doers are far away from the Lord, 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 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 of Dominion will be that of Allah: He will judge between them: so those who believe and work righteous deeds will be in Gardens of Delight. 56 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
