If We ever favour man with Our Mercy, and then take it away from him, he becomes utterly desperate, totally ungrateful. 9 And if We let him taste favour after harm has touched him, he says: 'All my ills are gone', and he suddenly becomes exultant and boastful, 10 Save those who persevere and do good works. Theirs will be forgiveness and a great reward. 11 You may haply omit some of what has been revealed to you, and may be disheartened because they say: "Why was no treasure sent down to him, or an angel accompanied him?" Yet you have been sent to warn alone, for God takes care of everything. 12 and so they assert, "[Muhammad himself] has invented this [Qur'an]!" Say [unto them]: "Produce, then, ten surahs of similar merit, invented [by yourselves,] and [to this end] call to your aid whomever you can, other than God, if what you say is true! 13 Then if they respond you not, know that it hath been sent down only with the Knowledge of Allah, and that there is no god but he; are ye Muslims then? 14 Whoever desires the life of this world and its comforts, We shall give them the full reward for their deeds in it, and not make any reduction in it. 15 They are those for whom there is nothing in the Hereafter but Fire; and vain are the deeds they did therein. And of no effect is that which they used to do. 16 Should they be compared with those whose Lord has given them a guidance which is testified by a witness from among their own people and by the Book of Moses, a guide and a mercy. Such people do believe in this guidance (in the Quran). Those who disbelieve (in the Quran) will have hell as their dwelling place. Thus, (Muhammad), have no doubt about it (the Quran). It is certainly the truth from your Lord, yet many people do not have faith. 17 Who doeth greater wrong than he who inventeth a lie concerning Allah? Such will be brought before their Lord, and the witnesses will say: These are they who lied concerning their Lord. Now the curse of Allah is upon wrong-doers, 18 who bar from God's way, desiring to make it crooked; they disbelieve in the world to come; 19 They had no power to frustrate Allah's design in the earth, nor did they have any protectors against Allah. Their chastisement will be doubled. They were unable to hear, nor could they see. 20 Those are they that have lost their souls, and that they forged has gone astray from them; 21 They will be, unnecessarily, the greatest losers in the Hereafter. 22 But those who believe and work righteousness, and humble themselves before their Lord,- They will be companions of the gardens, to dwell therein for aye! 23 ۞ The example of the two parties is that one is blind and deaf, and the other capable of seeing and hearing. Can the two be equals? Will you, then, not heed?' 24
