Say, "O people, I am sent only to give you clear warning." 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 50 "But those who strive against Our Signs, to frustrate them,- they will be Companions of the 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 That he may make that which the Satan casteth forth a temptation for those in whose heart is a disease and whose hearts are hardened - and the wrong-doers are in divergence far-off 53 And so those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is Allah the Guide of those who have believed to a straight path. 54 And those who disbelieve shall not cease to be in doubt concerning it until the hour overtakes them suddenly, or there comes on them the chastisement of a destructive day. 55 [All] sovereignty that Day is for Allah; He will judge between them. So they who believed and did righteous deeds will be in the Gardens of Pleasure. 56 But those who did not believe and called Our revelations lies, will be given disgraceful punishment. 57
