As He has said...

As He has said: 'On the Day when the heaven shall reel a (terrible) reeling, and the mountains shall fly an (awful) flight.” (Qur’an, 59:9-10) “And the earth will be changed with another one, i.e., with an earth upon which no sin would have been committed, open without any mountains and without any plant or grass, as He had revolved it in the first creation.” [^1] “And His 'Arsh' (Throne) will return upon the water, as it was in the beginning, independent with His Majesty and Power.” “At that time, Allah will create a very loud voice which will ring throughout the earth and heaven: “Whose is the kingdom this day?'1 No one will give any answer (as there will be none alive); then He will answer Himself creating a loud voice: '(It is) Of Allah, the One, the Subduer' (Qur’an, 40:16) I subdued all the creatures and gave them death; verily, I am Allah, there is no god except I alone, there is no partner for me nor any minister; and I made the creatures by my hand (Power) and I made them die by my Will; and I shall resurrect them by my Power.' “Then Allah will cause the second blowing of the Trumpet; the voice will come out from that side which is towards the heavens, and there will be none among the inhabitants of the heavens but will become alive and will stand as he was before; and will return the bearers of the 'Arsh' and the Garden and Fire will be brought forth, and the people will be gathered for reckoning.” Saying this,Imam Zaynul-Abedin (A) wept intensely.

[^2] Mentioning some of the events of this tradition, Allah says: “And when the Trumpet is blown, a single blast; and the earth and the mountains shall be borne away and crushed with a single crushing; on that Day shall happen the Great Event; and the heaven shall cleave asunder, so that on that day it shall be mere frail; and the angels shall be on the sides of it; and above them shall bear on that Day 'Arsh' of thy Lord eight (angels).” (Qur’an, 69:13-17) A great many Ayat s of the Qur'an give us the picture of that time, when the earth and heaven will be crushed and changed into new ones.

One who reads the Qur'an, with its meaning, and with open eyes, can understand it very easily. It is not possible to give here even one-tenth of those Ayat s. Why? Because the topic of Qiyamat is the most-often described subject in the Qur'an. Unfortunately, nowadays the Muslims treat it as the least important. They do harm to none except themselves.
