Tell them: "O men, it's my duty to warn you clearly." 49 And [know that] those who attain to faith and do righteous deeds shall be granted forgiveness of sins and a most excellent sustenance; 50 whereas those who strive against Our messages, seeking to defeat their purpose - they are destined for the blazing fire. 51 And We did not send before you any messenger or prophet except that when he spoke [or recited], Satan threw into it [some misunderstanding]. But Allah abolishes that which Satan throws in; then Allah makes precise His verses. And Allah is Knowing and Wise. 52 So that He may make what the Shaitan casts a trial for those in whose hearts is disease and those whose hearts are hard; and most surely the unjust are in a great opposition, 53 so that those who are given knowledge may realize that this is the truth from your Lord and thus believe in it, and so that in their hearts they may humbly submit to Him. God will surely guide the faithful to a straight path. 54 And the unbelievers will not cease to be in doubt of it, until the Hour comes on them suddenly, or there shall come upon them the chastisement of a barren day. 55 On that Day, all dominion shall [visibly] belong to God, He shall judge [all men and make a distinction] between them: thus, all who had attained to faith and did righteous deeds shall find themselves in gardens of bliss, 56 and the unbelievers who called Our revelations lies will suffer humiliating torment. 57
