If they belie you, say: 'I have my work, you have your work. You are quit of what I do, and I am quit of what you do' 41 Among them are some who (pretend to) listen to thee: But canst thou make the deaf to hear,- even though they are without understanding? 42 Some of them will look at you, but are you supposed to guide the blind even if they have no vision? 43 Verily Allah wrongeth not mankind in aught but mankind wrong themselves. 44 And on the Day when He shall gather them together, it will seem to them as if they had not tarried in the world longer than an hour of a day. They will recognize one another; lost indeed will be those who considered it a lie that they were destined to meet God, and did not follow the right path. 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 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, "When will this promise come to pass -- if you speak the truth?" 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 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 Will you believe in it only after it has overtaken you, although it was your wish to hurry it on?" 51 The wrong-doers will then be told: 'Suffer now the abiding chastisement. How else can you be rewarded except according to your deeds?' 52 They ask thee to tell them, 'Is it true?' Say: 'Yes, by my Lord! It is true; you cannot frustrate Him.' 53
