Those will have lost who deny the meeting with Allah, until when the Hour [of resurrection] comes upon them unexpectedly, they will say, "Oh, [how great is] our regret over what we neglected concerning it," while they bear their burdens on their backs. Unquestionably, evil is that which they bear. 31 Naught is the life of the world save a pastime and a sport. Better far is the abode of the Hereafter for those who keep their duty (to Allah). Have ye then no sense? 32 We know indeed that what they say certainly grieves you, but surely they do not call you a liar; but the unjust deny the communications of Allah. 33 Messengers indeed have been denied before thee, and they were patient under the denial and the persecution till Our succour reached them. There is none to alter the decisions of Allah. Already there hath reached thee (somewhat) of the tidings of the messengers (We sent before). 34 And if their backsliding is hard unto thee, then seek out, if thou canst, an opening into the earth or a ladder to the heaven that thou mayst bring unto them a sign. And had Allah willed, He would have assembled them unto the guidance; wherefore be not thou of the ignorant. 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 has no sign been sent down upon him from his Lord?” Say, “Indeed Allah is Able to send down a sign”, but most of them are totally ignorant. 37 And there is no creature on [or within] the earth or bird that flies with its wings except [that they are] communities like you. We have not neglected in the Register a thing. Then unto their Lord they will be gathered. 38 Those who disbelieve Our revelations are, in fact, deaf and dumb. They wander in darkness. God leads astray or guides to the right path whomever He wants. 39 Say thou: look ye now, were Allah's torment to come upon you, or the Hour come upon you, would ye then cry unto other than Allah, if ye are truthful? 40 No, on Him alone you will call, and He will remove that for which you call upon Him, if He will. Then you will forget what you associate (with Him). 41
