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 What is the life of this world but play and amusement? But best is the home in the hereafter, for those who are righteous. Will ye not then understand? 32 Well do We know that what such people say grieves thee indeed: yet, behold, it is not thee to whom they give the lie, but God's messages do these evildoers deny. 33 And apostles have assuredly been belied before thee, but they patiently bare that wherefore they were belied, and they were hurt, until Our succour came to them. And none can change the words of Allah; and assuredly there hath come unto thee some tidings of the sent ones. 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 ۞ It is only those who hear (with sincere hearts) that accept faith; and Allah will raise these people dead of heart, then towards Him they will be herded. 36 They also say, 'Why has no sign been sent down upon him from his Lord?' Say: 'Surely God is able to send down a sign, but most of them know not.' 37 And there is not an animal on the earth nor a fowl that flieth with its two wings but are communities like unto you. And We have not been remiss in respect of aught in the Book: then unto their Lord they shall be gathered. 38 Those who gave the lie to Our signs are deaf and dumb and blunder about in darkness. Allah causes whomsoever He wills to stray in error, and sets whomsoever He wills on the straight way.' 39 Say, "Tell me if the punishment of God came upon you or the Hour overtook you, would you call upon any other than God, if you are truthful?" 40 No, it is Him [alone] you would invoke, and He would remove that for which you invoked Him if He willed, and you would forget what you associate [with Him]. 41
