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 some of them give ear to thee; what, wilt thou make the deaf to hear, though they understand not? 42 And among them are those who look at you. But can you guide the blind although they will not [attempt to] see? 43 Lo! Allah wrongeth not mankind in aught; but mankind wrong themselves. 44 The Day when He will gather them, (it will be) as though they had lingered but an hour of the Day and they will recognize one another. Lost are those who belied the meeting with their Lord 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 ask: 'If what you say is true, when will this promise come' 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 ye thought: When His doom cometh unto you as a raid by night, or in the (busy) day; what is there of it that the guilty ones desire to hasten? 50 Will you, then, believe in it [only] after it has come to pass - [on the Day when you will be asked, 'Do you believe in it] now, after having [contemptuously] called for its speedy advent?' 51 Then it shall be said to those who were unjust: Taste abiding chastisement; you are not requited except for what you earned. 52 Yet they want to be informed if it is true. Say: "By my Lord, it is the truth. You cannot invalidate it." 53
