(Muhammad), tell them, "People, I am giving you a clear warning. 49 So those who believe and act righteously shall be granted forgiveness and an honourable sustenance, 50 And those who strive in Our signs with the intention of disputing, are the people of 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 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 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 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 all sovereignty shall be Allah's and He will judge among them. Then those who believed and acted righteously shall be in Gardens of Bliss. 56 While those who disbelieved and denied Our revelations, for them will be a shameful doom. 57
