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 And nothing is the life of this world but a play and a passing delight; and the life in the hereafter is by far the better for all who are conscious of God. Will you not, then, use your reason? 32 We certainly know that you (Muhammad) are sad about what they (the unbelievers) say. It is not you (alone) who has been accused of lying. The unjust have always rejected God's revelations. 33 Other messengers have been denied before you, and they bore their rejection and persecution steadfastly, until Our help came to them. There is no one who can change the words of God. You have already received some account of those messengers. 34 And if it distress thee that those who deny the truth turn their backs on thee - why, then, if thou art able to go down deep into the earth or to ascend a ladder unto heaven in order to bring them a [yet more convincing] message, [do so;] but [remember that] had God so willed, He would indeed have gathered them all unto [His] guidance. Do not, therefore, allow thyself to ignore [God's ways]. 35 ۞ Those who listen will surely answer. As for the dead, Allah will revive them. To Him they shall 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 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 they who give the lie to Our messages are deaf and dumb, in darkness deep. Whomever God wills, He lets go astray; and whomever He wills, He places upon a straight way. 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 "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
