When We bestow upon man a measure of Our grace and then take it away from him, he yields to despair and becomes ungrateful. 9 And if after adversity had come upon him, We let him taste prosperity, he says: 'Evil has left me' see, he is jubilant and boastful, 10 Not so do those who show patience and constancy, and work righteousness; for them is forgiveness (of sins) and a great reward. 11 (O Messenger!) Let it not happen that you omit (to expound) a portion of what was revealed to you. And do not be distressed that they will say: 'Why was a treasure not bestowed upon him?' or 'Why did no angel accompany him?' For you are merely a warner, whereas Allah has control over everything. 12 Do they, (the unbelievers), say that (Muhammad) has falsely ascribed (the Quran) to God? Ask them, "Compose ten chapters like (those of the Quran) and call on whomever you can for help besides God if you are true in your claim. 13 But if they do not respond to you, then know that this [Quran] is sent down with God's knowledge and that there is no deity but Him. Will you then surrender yourselves to Him? 14 We shall pay those who desire the present life and its adornments in full for the work they have done therein, they shall not be defrauded; 15 They are those for whom there is nothing in the Hereafter but the Fire: vain are the designs they frame therein, and of no effect are the deeds that they do! 16 Is he (to be counted equal with them) who relieth on a clear proof from his Lord, and a witness from Him reciteth it, and before it was the Book of Moses, an example and a mercy? Such believe therein, and whoso disbelieveth therein of the clans, the Fire is his appointed place. So be not thou in doubt concerning it. Lo! it is the Truth from thy Lord; but most of mankind believe not. 17 Who does greater wrong than the one who fabricates a lie against God? Such people shall be brought before their Lord, and the witnesses will say, "These are the ones who lied about their Lord." Surely God's rejection is merited by such wrongdoers. 18 Who debar (men) from the way of Allah and would have it crooked, and who are disbelievers in the Hereafter. 19 They can never frustrate God on earth, nor have they any protectors besides God. They will be subjected to double punishment, for they could neither hear nor see. 20 These are they who have lost their souls, and what they forged is gone from them. 21 Truly in the hereafter they are the greatest losers. 22 But those who believe and do things good, and are humble before their Lord, are men of Paradise where they will abide for ever. 23 ۞ These two kinds of man may be likened to the blind and deaf and the seeing and hearing. Can these two be deemed alike in [their] nature? Will you not, then, keep this in mind? 24
