It is necessary to have faith in all that will occur before Qiyamah that Almighty Allah has mentioned in the Qur’an. There is no need to interpret the respective verses to give way to the far-fetched explanations of heretics, and the doubts of the philosophers, as the Almighty Allah has said:

يَوْمَ نَطْوِي السَّمَاءَ كَطَيِّ السِّجِلِّ لِلْكُتُبِ

“On the day when We will roll up heaven like the rolling up of the scroll for writings” (21:104).

فَإِذَا انْشَقَّتِ السَّمَاءُ فَكَانَتْ وَرْدَةً كَالدِّهَانِ

“And when the heaven is rent asunder, and then becomes red like red hide” (55:37).

Then He said:

وَانْشَقَّتِ السَّمَاءُ فَهِيَ يَوْمَئِذٍ وَاهِيَةٌ

“And the heaven shall cleave asunder, so that on that day it shall be frail” (69:16).

Then He said:

يَوْمَ تَمُورُ السَّمَاءُ مَوْرً

“On the day when the heaven shall move from side to side” (52:9).

Regarding stars also, He has said in many places that their light will fade, as will fade the lights of the sun and moon, and they will fall from the sky. The sun and the moon will decline. Sun and moon will come together:

وَتَكُونُ الْجِبَالُ كَالْعِهْنِ

“And the mountains shall be as tufts of wool” (70:9).

They will separate from each other. They will be like scattered dust. They will be levelled to the earth. A great quaking will occur in the earth; such that all the buildings will be razed. And the earth would become levelled.

Moreover, He said:

وَيَسْأَلُونَكَ عَنِ الْجِبَالِ فَقُلْ يَنْسِفُهَا رَبِّي نَسْفًا

“And they ask you about the mountains. Say: My Lord will carry them away from the roots” (20:105).

فَيَذَرُهَا قَاعًا صَفْصَفًا

“Then leave it a plain, smooth level” (20:106).

لَا تَرَىٰ فِيهَا عِوَجًا وَلَا أَمْتًا

“You shall not see therein any crookedness or unevenness” (20:107).

‘Ali Ibn Ibrahim has in his Tafsir, narrated through authentic chains of narrators from Imam Muhammad al-Baqir (‘a) that when the Almighty Allah wants to gather the people, He will ask the announcer to call out and He will gather all Jinns and men in a single moment in one place. Then He will bring the first heaven and place it behind the people; then bring the second heaven, which is twice the size of the first; in the same sequence He will bring down all the heavens and put them around all the people. After that, a cloud will come down with angels and the caller will announce the following verse:

يَا مَعْشَرَ الْجِنِّ وَالْإِنْسِ إِنِ اسْتَطَعْتُمْ أَنْ تَنْفُذُوا مِنْ أَقْطَارِ السَّمَاوَاتِ وَالْأَرْضِ فَانْفُذُوا لَا تَنْفُذُونَ إِلَّا بِسُلْطَانٍ

“O assembly of the jinn and the men! If you are able to pass through the regions of the heavens and the earth, then pass through; you cannot pass through, but with authority” (55:33).

Then Imam (‘a) wept and the narrator asked: Where will the Messenger of Allah (S), Amir al-Mu’minin (‘a) and their Shi’as be at that time? He replied: They would be located on many hills, which are more fragrant than Musk. They will be atop pulpits of effulgence. All would be aggrieved, but they will not be disappointed. All would be terrified, but they will not be terrified. Then the Imam recited:

مَنْ جَاءَ بِالْحَسَنَةِ فَلَهُ خَيْرٌ مِنْهَا وَهُمْ مِنْ فَزَعٍ يَوْمَئِذٍ آمِنُونَ

“Whoever brings good, he shall have better than it; and they shall be secure from terror on the day” (27:89).

Then he said: By Allah, in this verse, the ‘good’ implies the Wilayat of Amir al-Mu’minin (‘a).

‘Ali Ibn Ibrahim has narrated from the Imam that on Judgment Day, the Almighty Allah will gather all people in one place on the earth. Then He will inspire the first heaven to descend with all those who are on it. So, the first heaven will descend along with twice the numbers that are in the earth. Then the second heaven will descend, along with twice the number, which are in the first heaven.

In this way will descend the folks of all heavens, who in number are twice their predecessors. The Jinns and men will be present in seven veils. A caller from the angels will call out to them with the verse mentioned above. All of them will see that the angels have surrounded them from all sides, and they cannot escape in any way.
