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 And there are among them such as [pretend to] listen to thee: but canst thou cause the deaf to hearken even though they will not use their reason? 42 And of them some look towards you; will you, then, guide the blind, even though they can see nothing? 43 Surely God does not wrong anyone; 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 show you (in your lifetime, O Muhammad SAW) some of what We promise them (the torment), - or We cause you to die, - still unto Us is their return, and moreover Allah is Witness over what they used to do. 46 Every nation has its Messenger; then, when their Messenger comes, justly the issue is decided between them, and they are not wronged. 47 They say:'If what you promise is true, when will this threat be fulfilled?' 48 Tell them: 'I have no power to harm or benefit even myself, except what Allah may will. There is an appointed term for every people; and when the end of their term comes, neither can they put it off for an hour, nor can they bring it an hour before. 49 Say: "Have you ever thought if His punishment befalls you at night or in the day, what would the sinners do to despatch it? 50 Is it only when this chastisement has actually overtaken you that you will believe in it? (And when the chastisement will surprise you), you will try to get away from it, although it is you who had sought to hasten its coming.' 51 whereupon those who [in their lifetime] were bent on evildoing will be told, 'Taste suffering abiding! Is this requital anything but the just due for what you were wont to do?" 52 They ask you to tell them if it is true. Say: 'Yes, by my Lord! It is true, and you cannot frustrate it' 53
