Those who denied their meeting with Allah, have indeed failed; to the extent that when the Last Day suddenly came upon them they said, “Woe to us that we failed to believe in it” – and they carry their burdens on their backs; what an evil burden they carry! 31 The worldly life is but useless amusement and sport (compared to) the life hereafter which is far better and is only for the pious. Will you not then understand? 32 We know well how their talk grieveth thee, though in truth they deny not thee (Muhammad) but evil-doers flout the revelations of Allah. 33 Messengers indeed were belied before you, yet they became patient with that which they were belied, and were hurt until Our help came to them. There is none to alter the Words of Allah; and there has already come to you some news of the Messengers. 34 If their aversion still weighs upon you, seek out a tunnel (going deep) into the earth, or a ladder reaching out to the skies, and bring them a sign: (Even then they will not believe). If God had willed He would have brought them all to the right path. So be not like the pagans. 35 ۞ Only those who have understanding will accept your faith. (Those who have no understanding) are like the dead whom God will resurrect and to Him will all return. 36 And they said: "Why is not a sign sent down to him from his Lord?" Say: "Allah is certainly Able to send down a sign, but most of them know not." 37 there is not an animal that moves about on the earth, nor a bird that flies on its two wings, but are creatures like you. We have left out nothing in the Book -- they shall all be gathered before their Lord. 38 Those who deny Our revelations are deaf and dumb in darkness. Whom Allah will sendeth astray, and whom He will He placeth on a straight path. 39 Say, "Have you considered: if there came to you the punishment of Allah or there came to you the Hour - is it other than Allah you would invoke, if you should be truthful?" 40 No, it is Him [alone] you would invoke, and He would remove that for which you invoked Him if He willed, and you would forget what you associate [with Him]. 41
