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 will listen to you, but are you supposed to make the deaf hear even if they have no understanding? 42 And of them are some who look at thee, so canst thou guide the blind, even though they see not? 43 Verily, God does not do the least wrong unto men, but it is men who 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 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 say: "When is this promise going to come, if what you say is true?" 48 Say: "I have no power over my own gain or loss other than what God may please." Every people have a certain term. When their time is come they can neither delay it an hour nor advance it a moment forward. 49 Say: 'Have you considered? If His chastisement comes upon you by night or day, what part of it will the sinners seek to hasten? 50 Is it (only) then, when it hath befallen you, that ye will believe? What! (Believe) now, when (until now) ye have been hastening it on (through disbelief)? 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 Yet they want to be informed if it is true. Say: "By my Lord, it is the truth. You cannot invalidate it." 53
