Tell them: "O men, it's my duty to warn you clearly." 49 And those who have believed and done righteous deeds - for them is forgiveness and noble provision. 50 And those who strive in Our signs with the intention of disputing, are the people of fire. 51 Never did We send a messenger or a prophet before thee, but, when he framed a desire, Satan threw some (vanity) into his desire: but Allah will cancel anything (vain) that Satan throws in, and Allah will confirm (and establish) His Signs: for Allah is full of Knowledge and Wisdom: 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 And the disbelievers will always be in doubt of it, to the extent that the Last Day will suddenly come upon them, or will come upon them the punishment of a day the result of which is not at all good for them. 55 On that day it is God who will be the Absolute King and Judge of (mankind). The righteously striving believers will go to Paradise 56 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
