And if they belie thee, say thou: unto me my work, and unto you your work: ye are quit of that which I work and I am quit of that which ye work. 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 those who look at you. But can you guide the blind although they will not [attempt to] see? 43 Surely God wrongs not men anything, but themselves men wrong. 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 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 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 say: "When will this promise come to pass,- if ye speak the truth?" 48 Say: "I have no power over any harm or profit to myself except as Allah willeth. To every people is a term appointed: when their term is reached, not an hour can they cause delay, nor (an hour) can they advance (it in anticipation)." 49 Say: "Tell me, - if His torment should come to you by night or by day, - which portion thereof would the Mujrimun (disbelievers, polytheists, sinners, criminals) hasten on?" 50 Will you believe in it only after it has overtaken you, although it was your wish to hurry it on?" 51 Then will the sinners be told: "Now taste everlasting torment. Should you be rewarded for anything else but what you did?" 52 And they ask information of you, [O Muhammad], "Is it true?" Say, "Yes, by my Lord. Indeed, it is truth; and you will not cause failure [to Allah]." 53
