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 those of them who hear you, but can you make the deaf to hear though they will not understand? 42 And among them are some who look at thee: but canst thou guide the blind,- even though they will not see? 43 Verily, God does not do the least wrong unto men, but it is men who wrong themselves. 44 And on the day when He will gather them as though they had not stayed but an hour of the day, they will know each other. They will perish indeed who called the meeting with Allah to be a lie, and they are not followers of the right direction. 45 Whether We show you something of what We have promised them or cause you to die [before that], to Us they shall return. God is Witness to all that they do. 46 And for every nation there is a messenger. And when their messenger cometh (on the Day of Judgment) it will be judged between them fairly, and they will not be wronged. 47 They ask: 'If what you say is true, when will this promise come' 48 (Muhammad), tell them, "I have no control over my suffering or benefits unless God wills. Every nation is destined to live for an appointed time. They can neither delay that time nor can they cause it to come sooner. 49 Say, "Have you considered: if His punishment should come to you by night or by day - for which [aspect] of it would the criminals be impatient?" 50 Then is it that when it has [actually] occurred you will believe in it? Now? And you were [once] for it impatient 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 And some people ask thee, "Is all this true?" Say: "Yea, by my Sustainer! It is most certainly true, and you cannot elude [the final reckoning]!" 53
