(Muhammad), they will ask you about the mountains. Tell them, "My Lord will grind them to powder 105 And leave it as an empty plain, 106 "You will see therein nothing crooked or curved." 107 On that Day, all will follow the summoning Voice from which there will be no escape; and all sounds will be hushed before the Most Gracious, and thou wilt hear nothing but a faint sough in the air. 108 On that day no intercession shall avail, except the one for whom the Most Beneficent (Allah) has given permission and whose word is acceptable to Him. 109 He knoweth that which is before them and that which is behind them, and they encompass it not with their knowledge. 110 ۞ And [on that Day] all faces will be humbled before the Ever-Living, the Self-Subsistent Fount of All Being; and undone shall be he who bears [a burden of] evildoing 111 but he who does good works, being a believer, shall fear no harm nor any injustice." 112 Even so We have sent it down as an Arabic Koran, and We have turned about in it something of threats, that haply they may be godfearing, or it may arouse in them remembrance. 113 High above all is Allah, the King, the Truth! Be not in haste with the Qur'an before its revelation to thee is completed, but say, "O my Lord! advance me in knowledge." 114 And certainly We gave a commandment to Adam before, but he forgot; and We did not find in him any determination. 115
