Say (O Muhammad): "O people! I have been sent to you only as a plain warner (before the Doom strikes you)." 49 Those who believe and do good works, for them is pardon and a rich provision; 50 but those who strive to void Our verses, thinking they have escaped, shall be the people of Hell' 51 Never sent We a messenger or a prophet before thee but when He recited (the message) Satan proposed (opposition) in respect of that which he recited thereof. But Allah abolisheth that which Satan proposeth. Then Allah establisheth His revelations. Allah is Knower, 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 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 The unbelievers will never cease to doubt it until the Hour overtakes them suddenly or the punishment of the Barren Day comes upon them. 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 and the unbelievers who called Our revelations lies will suffer humiliating torment. 57
