If We allow man to enjoy Our favours, and then take them away from him, he becomes despondent and ungrateful. 9 And if We cause him to taste grace after some misfortune that had befallen him, he saith: The ills have gone from me. Lo! he is exultant, boastful; 10 Except those who patiently endured and did good deeds; for them is forgiveness, and a great reward. 11 You may [feel the inclination] to leave aside a part of what is revealed to you and you may be distressed because they say, "Why has no treasure been sent down to him, why has no angel come with him?" But you are only to give warning. God is the guardian of all things. 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 But if they do not answer you, then know that it is revealed by Allah's knowledge and that there is no god but He; will you then submit? 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 These are they for whom there is not in the Hereafter save the Fire; to naught shall come that which they have performed, and vain is that which they have been working 16 Is he then who has with him clear proof from his Lord, and a witness from Him recites it and before it (is) the Book of Musa, a guide and a mercy? These believe in it; and whoever of the (different) parties disbelieves in it, surely it is the truth from your Lord, but most men do not believe. 17 And who does greater evil than he who forges against God a lie? Those shall be presented before their Lord, and the witnesses will say, 'Those are they who lied against their Lord.' Surely the curse of God shall rest upon the evildoers 18 upon those who bar people from the way of Allah, and seek in it crookedness, and disbelieve in the Hereafter. 19 They will in no wise frustrate (His design) on earth, nor have they protectors besides Allah! Their penalty will be doubled! They lost the power to hear, and they did not see! 20 Such are they who have lost their souls, and that which they used to invent hath failed them. 21 In the Hereafter, it is they who shall be the greatest losers. 22 Whereas those who believe and do good deeds and humble themselves before their Lord, they are the companions of Paradise, and there they shall live for ever. 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
