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 The life of this world is nothing but a sport and a pastime, and the life of the Hereafter is far better for those who seek to ward off their ruin. 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 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 If their turning away is hard upon you, seek if you can, a tunnel in the ground or a ladder to the sky by which you can bring them a sign. Had Allah willed, He would gather them to guidance. Do not then be among the ignorant. 35 ۞ Those who listen will surely answer. As for the dead, Allah will revive them. To Him they shall return. 36 And they say: "Why has no miraculous sign been bestowed on him from on high by his Sustainer?" Say: "Behold, God has the power to bestow any sign from on high." Yet most human beings are unaware of this 37 No creature is there crawling on the earth, no bird flying with its wings, but they are nations like unto yourselves. We have neglected nothing in the Book; then to their Lord they shall be mustered. 38 And those who deny Our signs are deaf and dumb in realms of darkness; Allah may send astray whomever He wills; and may place on the Straight Path whomever He wills. 39 (Muhammad), say to them, "Should God afflict you with torment, or should the Day of Judgment arrive, if what you claim is true, could you then seek help from any one other than God? 40 "Nay,- On Him would ye call, and if it be His will, He would remove (the distress) which occasioned your call upon Him, and ye would forget (the false gods) which ye join with Him!" 41
