We grant a favor to the human being and then take it away from him. He becomes despairing and ungrateful. 9 If We let him taste Our favours after adversity, he says: "Misfortune has left me," and begins to brag and exult, 10 Save those who persevere and do good works. Theirs will be forgiveness 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 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 To those who desire the life of this world and its many allures, We shall pay them in full for their acts herein and will not withold any thing. 15 They are the ones who shall have nothing in the Hereafter except Fire. (There they shall come to know) that their deeds in the world have come to naught; and that whatever they have done is absolutely useless. 16 Can they be (like) those who accept a Clear (Sign) from their Lord, and whom a witness from Himself doth teach, as did the Book of Moses before it,- a guide and a mercy? They believe therein; but those of the Sects that reject it,- the Fire will be their promised meeting-place. Be not then in doubt thereon: for it is the truth from thy Lord: yet many among men do not believe! 17 And who is more unjust than the one who fabricates a lie against Allah? They will be presented before their Lord, and the witnesses* will say, “These are they who lied concerning their Lord; the curse of Allah be upon the unjust!” (* The Prophets and angels.) 18 Who averted [people] from the way of Allah and sought to make it [seem] deviant while they, concerning the Hereafter, were disbelievers. 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 They have lost their souls and their false deities will turn away from them. 21 In the Hereafter, it is they who shall be the greatest losers. 22 But those who believe, and do righteous deeds, and have humbled themselves unto their Lord -- they shall be the inhabitants of Paradise, therein dwelling forever. 23 ۞ The example of the two groups is like one being blind and deaf, and the other seeing and hearing; are they equal in condition? So do you not ponder? 24
