سورة الرحمن

Ali ibn Ibrahim (may Allah have mercy on him): When the Day of Resurrection comes, the sky of the world will encompass the earth, and the second heaven will encompass the sky of the world, and the third heaven will encompass the second, and every heaven will encompass the one next to it. Then a caller will call out: یا مَعْشَرَ الْجِنِّ وَ الْإِنْسِ... بِسُلْطانٍ [O assembly of the jinn and the men... except with authority] — meaning, with proof and evidence.

Imam Sadiq (peace be upon him): When the Day of Resurrection [is established], Allah will gather the servants on one plain of the earth. That is because He will reveal to the sky of the world: 'Descend with whoever is in you.' So the inhabitants of the sky of the world will descend equal to twice the jinn, humans and angels that are on earth. Then the inhabitants of the second heaven will descend twice the amount of all [those who have already descended], and it will keep on like this until the inhabitants of all seven heavens descend, and the jinn and humans will be placed within seven canopies of angels. Then a caller will cry out: یا مَعْشَرَ الْجِنِّ وَ الْإِنْسِ إِنِ اسْتَطَعْتُمْ أَنْ تَنْفُذُوا مِنْ أَقْطارِ السَّماواتِ وَ الْأَرْضِ فَانْفُذُوا لا تَنْفُذُونَ إِلاَّ بِسُلْطان [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]. At that moment they will look, and suddenly [they will see] that seven ranks of angels which surround them have encompassed them.

Imam Baqir (peace be upon him): When it becomes Allah's will (bada) to make His creation manifest and gather them for the matter which is inevitable, He will command a caller, and he will call out, and the humans and jinn will gather together in less than the blink of an eye. Then He will command the sky of the world, and it will descend, and He Himself will be behind the people. He will command the second heaven, and it will descend, and it will be twice the one next to it. When the inhabitants of the sky of the world see it, they will say: 'Our Lord has come.' It will be said: 'No, but He is coming' — meaning His command and order — until every heaven descends, each one behind the other, and each one twice the one before it. Then Allah's command comes ثُمَّ یَنْزِلَ اللَّهُ فِی ظُلَلٍ مِنَ الْغَمامِ وَ الْمَلائِکَةُ وَ قُضِیَ الْأَمْرُ وَ إِلَی اللهِ تُرْجَعُ الْأُمُورُ [in canopies of clouds along with the angels, and the matter will be decided, and to Allah all matters return]. Then Allah will command a caller to call out: یَا مَعْشَرَ الجِنِّ و الإِنسِ إِنِ اسْتَطَعْتُمْ أَن تَنفُذُوا مِنْ أَقْطَارِ السَّمَاواتِ و الأَرْضِ فَانفُذُوا لا تَنفُذُونَ إِلا بِسُلطَانٍ [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].
