Say thou: mankind! I am unto you only a warner manifest. 49 Then (as for) those who believe and do good, they shall have forgiveness and an honorable sustenance. 50 And those who strive against Our signs to void them -- they shall be the inhabitants of Hell. 51 Never did We send a Messenger or a Prophet before you (O Muhammad), but that whenever he had a desire, Satan interfered with that desire. Allah eradicates the interference of Satan and strengthens His Signs. Allah is All-Knowing, 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 At the same time those who have been given knowledge may know that this is the truth from your Lord, and come to believe in it, and their hearts become submissive to Him. Verily God guides those who believe, to the even 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 On that Day all control will belong to God. He will judge between them. Those who believe and do good deeds shall enter the Gardens of Bliss, 56 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
