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 but a sport and a pastime. Surely the Home of the Hereafter is best for those who fear God. Will you not 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 you find their rejection hard to bear, then seek a tunnel into the ground or a ladder into the sky, if you can, and bring them a sign. Had God so willed, He would indeed have given them all [His] guidance. So do not be among the ignorant. 35 ۞ Only those respond who hearken. And as to the dead, Allah will raise them, and thereafter unto Him they shall be returned. 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 lives) on the earth, nor a being that flies on its wings, but (forms part of) communities like you. Nothing have we omitted from the Book, and they (all) shall be gathered to their Lord in the end. 38 And those who belie our signs are deaf and dumb, in darkness. Whomsoever Allah willeth He sendeth astray, and whomsoever He willeth He putteth on the right path. 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 "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
