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 there are among them such as [pretend to] look towards thee: but canst thou show the right way to the blind even though they cannot see? 43 Verily Allah wrongeth not mankind in aught but mankind wrong themselves. 44 And of the Day whereon He shall gather them, as though they had tarried not save an hour of the day they shall mutually recognize. Lost surely are those who belie the meeting with Allah and they were not such as to be guided. 45 Whether We let you see some of that with which We promised them, or We call you to Us, to Us they shall return. Allah is witness of the things they do. 46 A Messenger is sent to every people; and when their Messenger comes, the fate of that people is decided with full justice; they are subjected to no wrong. 47 And they say, "When is [the fulfillment of] this promise, if you should be truthful?" 48 Say: 'I have no power to benefit or harm myself except as Allah wills. To every nation is a fixed term and when their term comes they cannot delay it for an hour, nor can they bring it forward. 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, 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 will be said to the evildoers: 'Taste the chastisement of eternity! Are you recompensed for aught but that you have been earning?' 52 They ask you if what you say is true? Tell them: 'Yes, by my Lord, this is altogether true, and you have no power to prevent the chastisement from befalling.' 53
