And those who disbelieve say: What! when we have become dust and our fathers (too), shall we certainly be brought forth? 67 We and our fathers were promised this before; these are but old stories." 68 Say: 'Journey in the land and see what was the end of the sinners' 69 And grieve not over them or be in distress from what they conspire. 70 And they ask: 'When will this promise come, if what you say is true' 71 Say: It may be that a part of that which ye would hasten on is close behind you. 72 But verily thy Lord is full of grace to mankind: Yet most of them are ungrateful. 73 Verily your Lord knows all that their hearts conceal as well as all that they reveal. 74 There is nothing that is hidden - be it in the heaven or the earth - but is recorded in a Clear Book. 75 Verily this Qur'an recounteth with truth unto the Children of Isra'il much of that wherein they differ. 76 And truly, it (this Quran) is a guide and a mercy to the believers. 77 Surely your Lord will judge between them by his judgment, and He is the Mighty, the knowing. 78 Wherefore put thy trust in Allah; verily thou art on manifest truth. 79 Verily thou canst not make the dead hear, nor canst thou make the deaf hear the call when they flee turning their backs. 80 You cannot guide the straying blind ones. You can only make hear those who believe in Our revelations submissively. 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
