Those who do not believe in the Day of Judgment have incurred upon themselves a great loss. When the Day of Judgment suddenly comes upon them, they will sink under the burden of their sins in grief for their neglecting that day. Terrible indeed will be their burden! 31 And this world's life is naught but a play and an idle sport and certainly the abode of the hereafter is better for those who guard (against evil); do you not then understand? 32 (O Muhammad!) We know indeed that the things they say grieve you, though in truth it is not you whom they give the lie to, but it is the signs of Allah that these wrong-doers reject. 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 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 they who listen [with their hearts] can respond to a call; and as for the dead [of heart,] God [alone] can raise them from the dead, whereupon unto Him they shall return. 36 And they say: Why has not a sign been sent down to him from his Lord? Say: Surely Allah is able to send down a sign, but most of them do not know. 37 And there is no animal that walks upon the earth nor a bird that flies with its two wings but (they are) genera like yourselves; We have not neglected anything in the Book, then to their Lord shall they be gathered. 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: "Can you see yourselves invoking any but God when God's chastisement befalls you [in this world,] or the Last Hour comes upon you? [Tell me this,] if you are men of truth! 40 No; upon Him you will call, and He will remove that for which you call upon Him if He Will, and you will forget that you associate with Him. 41
