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 that what they say grieves you. It is not you that the wrongdoers are rejecting, rather it is the signs of God that they reject. 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 And if their evasion is difficult for you, then if you are able to seek a tunnel into the earth or a stairway into the sky to bring them a sign, [then do so]. But if Allah had willed, He would have united them upon guidance. So never be 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 They ask, "Why has no sign been sent down to him from his Lord?" Say, "God alone has the power to send down a sign." But most of them do not understand: 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 Those who reject our signs are deaf and dumb,- in the midst of darkness profound: whom Allah willeth, He leaveth to wander: whom He willeth, He placeth on the way that is straight. 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 Indeed, it is on Him that you would call, and He could remove that [affliction] which made you call on Him, if He will, and then you would forget [the false deities] which you associate with Him!" 41
