If they charge thee with falsehood, say: "My work to me, and yours to you! ye are free from responsibility for what I do, and I for what ye 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 Indeed, Allah does not wrong the people at all, but it is the people who are wronging 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 Every nation has its Messenger; then, when their Messenger comes, justly the issue is decided between them, and they are not wronged. 47 And yet, they [who deny the truth] are wont to ask, "When is that promise [of resurrection and judgment] to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 48 Say (O Muhammad SAW): "I have no power over any harm or profit to myself except what Allah may will. For every Ummah (a community or a nation), there is a term appointed; when their term is reached, neither can they delay it nor can they advance it an hour (or a moment)." (Tafsir Al-Qurtubi). 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 then, that when it has actually befallen, that you will believe in it? What! Now (you believe)? And you used (aforetime) to hasten it on!" 51 The unjust will be told, "Suffer the everlasting torment. Do you expect a recompense other than what you deserve? 52 They ask thee to tell them, 'Is it true?' Say: 'Yes, by my Lord! It is true; you cannot frustrate Him.' 53
