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 promised this, forsooth, we and our fathers. (All) this is naught but fables of the men of old. 68 Say, "Roam across the earth and observe what was the end of the sinful ones." 69 And grieve not over them or be in distress from what they conspire. 70 They also say: "Tell us when this threat will come to pass, if you are truthful." 71 Say thou: belike close behind you may be some of that which ye would hasten on. 72 But verily thy Lord is full of grace to mankind: Yet most of them are ungrateful. 73 And verily thine Lord knoweth whatsoever their breasts conceal and whatsoever they make known. 74 There is not a thing hidden in the heaven and earth except that it is in a Clear Book. 75 Verily this Qur'an doth explain to the Children of Israel most of the matters in which they disagree. 76 And most surely it is a guidance and a mercy for the believers. 77 Surely your Lord in His wisdom will decide between them. He is all-mighty and all-knowing. 78 So put your trust in Allah for you are on the manifest truth. 79 [But,] verily, thou canst not make the dead hear: and [so, too,] thou canst not make the deaf [of heart] hear this call when they turn their backs [on thee] and go away, 80 Nor do you guide the blind out of their error, nor do you make any to hear, except those who believe in Our verses and are Muslims. 81 ۞ Now, [as for the deaf and blind of heart -] when the word [of truth] stands revealed against them, We shall bring forth unto them out of the earth a creature, which will tell them that mankind had no real faith in Our messages. 82
