If they cry lies to thee, then do thou say: 'I have my work, and you have your work; you are quit of What I do, and I am quit of what you do.' 41 And of them are some who listen unto thee. But canst thou make the deaf to hear even though they apprehend not? 42 And among them are some who look at thee: but canst thou guide the blind,- even though they will not see? 43 Lo! Allah wrongeth not mankind in aught; but mankind 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 (during your lifetime) some of the chastisement with which We threaten them, or We call you unto Us (before the chastisement strikes them), in any case they are bound to return to Us. Allah is witness to all what they do. 46 And for every Ummah (a community or a nation), there is a Messenger; when their Messenger comes, the matter will be judged between them with justice, and they will not be wronged. 47 They say:'If what you promise is true, when will this threat be fulfilled?' 48 Say: I have no power to hurt or benefit myself, save that which Allah willeth. For every nation there is an appointed time. When their time cometh, then they cannot put it off an hour, nor hasten (it). 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 Will you believe it when it comes to pass? Indeed, you will believe it then. How impatient you were to hasten it! 51 Then it will be said to those who had wronged, "Taste the punishment of eternity; are you being recompensed except for what you used to earn?" 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
