Those who deny the truth say, "When we have turned to dust like our fathers, shall we be brought back to life again? 67 We were told about this and so were our forefathers before us. But these are no more than fairy tales that have been recounted from ancient times." 68 Say: Travel in the earth, then see how was the end of the guilty. 69 And grieve you not for them, nor be straitened (in distress) because of what they plot. 70 They also say: "Tell us when this threat will come to pass, if you are truthful." 71 Say: "Perhaps that which you wish to hasten on, may be close behind you. 72 But verily thy Lord is full of grace to mankind: Yet most of them are ungrateful. 73 The Lord knows full well what they conceal in their hearts and what they disclose: 74 There is not a thing hidden in the heaven and earth except that it is in a Clear Book. 75 Surely this Koran relates to the Children of Israel most of that concerning which they are at variance; 76 and it is a guidance and mercy for the believers. 77 Verily thy Lord will decide between them by His Decree: and He is Exalted in Might, All-Knowing. 78 Therefore rely on Allah; surely you are on the clear truth. 79 Thou shalt not make the dead to hear, neither shalt thou make the deaf to hear the call when they turn about, retreating. 80 just as thou canst not lead the blind [of heart] out of their error; none canst thou make hear save such as [are willing to] believe in Our messages, and thus surrender themselves unto Us. 81 ۞ When the word about them comes true We shall make a creature appear to them on earth who will tell them that people had no faith in Our revelations. 82
