And if they call you a liar, say: My work is for me and your work for you; you are clear of what I do and I am clear of what you do. 41 Some of them will listen to you, but are you supposed to make the deaf hear even if they have no understanding? 42 And among them are some who look at you, but can you guide the blind, even though they see not? 43 Indeed, Allah does not wrong mankind a thing, but they wrong themselves. 44 And on the day when He shall gather them together, (when it will seem) as though they had tarried but an hour of the day, recognising one another, those will verily have perished who denied the meeting with Allah and were not guided. 45 Whether We let you see some of that with which We promised them, or We call you to Us, to Us they shall return. Allah is witness of the things they do. 46 For every people there is an apostle; and when their apostle is come the matter is decided between them equitably, and no one is wronged. 47 They say: "When is this promise going to come, if what you say is true?" 48 Say [O Prophet]: "It is not within my power to avert harm from, or bring benefit to, myself, except as God may please. For all people a term has been set: when the end of their term approaches, they can neither delay it by a single moment, nor hasten it." 49 Say: "Have you ever considered [how you would feel] if His chastisement were to befall you by night or by day? What could there be in that prospect that people lost in sin should wish to hasten? 50 And when it overtakes you, is it then that you will believe in it, now, when you already try to hasten it! 51 Then it will be said to them who wronged themselves: "Taste you the everlasting torment! Are you recompensed (aught) save what you used to earn?" 52 They ask you if what you say is true? Tell them: 'Yes, by my Lord, this is altogether true, and you have no power to prevent the chastisement from befalling.' 53
