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 Some of them listen to you: But can you make the deaf hear who do not understand a thing? 42 Some of them look fixedly at you; but can you make the blind see, bereft as they are of sight? 43 God does not do the least bit of injustice to anyone but people wrong themselves. 44 The day He will gather them together it will appear to them that they had lived (in the world) but an hour of a day to make each other's acquaintance. Verily those who deny the meeting with God will be lost, and not find the way. 45 Whether We show thee a part of that We promise them, or We call thee unto Us, to Us they shall return; then God is witness of the things 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 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: Tell me if His punishment overtakes you by night or by day! what then is there of it that the guilty would hasten on? 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 The wrong-doers will then be told: 'Suffer now the abiding chastisement. How else can you be rewarded except according to your deeds?' 52 They ask you to tell them if it is true. Say: 'Yes, by my Lord! It is true, and you cannot frustrate it' 53
