We believe that when Allah Almighty decides to bring this world to an end, He commands the angel to blow the trumpet. Thereupon, all that is in the heavens and on earth will get stunned, except whom Allah wills. Our Lord, Exalted be He, says: {The Trumpet will be blown and all those in the heavens and all those on earth will get stunned, except whom Allah wills. Then it will be blown again, and at once they will be standing, looking on.} [Surat az-Zumar: 68] And the Prophet (may Allah's peace and blessings be upon him) said: "Then, the trumpet will be blown and no one will hear that but he will bend his neck to one side and raise it from the other side. The first one to hear that trumpet will be the person who will be busy in setting right the tank meant for providing water to the camels. He will get stunned and the other people will also get stunned." [Narrated by Muslim (2940)] --
In another Hadīth, the Prophet (may Allah's peace and blessings be upon him) said: "The Hour will come (so suddenly) that two persons spreading a garment between them will not be able to finish their bargain, nor will they be able to fold it up. The Hour will come while a man is carrying the milk of his she-camel, but cannot drink it. The Hour will come when someone is not able to prepare the tank to water his livestock from it; and the Hour will come when one of you has raised his food to his mouth but cannot eat it."
Allah Almighty will cause whomever He wills among His creation to perish, and none will remain but Him, Exalted be He. Our Lord says: {Everyone on earth will perish, but there will remain the Face of your Lord, full of Majesty and Honor.} [Surat ar-Rahmān: 26-27] Allah Almighty also says: {Do not supplicate with Allah another god; none has the right to be worshiped except Him. Everything will perish except Him. His is the Judgment and to Him you will all be brought back.} [Surat al-Qasas: 88] In another verse, He, Exalted be He, says: {The Day when they will be brought forth, nothing about them will be hidden from Allah. [He will say]: "To whom does the dominion belong this Day? To Allah, the One, the Subjugator!"} [Surat Ghāfir: 16]
Then, Allah Almighty will send down rain out of which the bodies of people will grow. The Prophet (may Allah's peace and blessings be upon him) said: "Then, Allah will send down rain which will be like drizzle, or like shadow - Nu‘mān, a narrator of this Hadīth, is in doubt - and out of which the bodies of people will grow. Then, it will be blown a second time, and they will stand up looking on." [Narrated by Muslim (2940)]
Then, Allah, the Exalted, will command the angel to blow the trumpet a second time. He, Glorified be He, says: {Then it will be blown again, and at once they will be standing, looking on.} [Surat az-Zumar: 68]
The Prophet (may Allah's peace and blessings be upon him) demonstrated the amount of time between the two blows. Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Between the two blows, there will be forty. Everything of the human body will decay except the coccyx bone, from which Allah will reconstruct the whole body." [Narrated by Al-Bukhāri (4814) and Muslim (2955)]
We believe in what the Prophet (may Allah's peace and blessings be upon him) told us with regard to the heavens and the earth on the Day of Judgment. Ibn Mas‘ūd (may Allah be pleased with him) reported: A Jewish rabbi came to the Messenger of Allah (may Allah’s peace and blessings be upon him) and said: "O Muhammad, we learned that Allah will place the heavens on one finger, and the earths on one finger, and the trees on one finger, and the water and dust on one finger, and all other creatures on one finger. Then, He will say: 'I am the King.'" Thereupon, the Prophet (may Allah's peace and blessings be upon him) laughed until his premolar teeth became visible, in confirmation of the rabbi’s words. Then, the Messenger of Allah (may Allah's peace and blessings be upon him) recited: {They did not revere Allah His true reverence. On the Day of Resurrection, the whole earth will be in His Grip, and the heavens will be rolled up in His Right Hand. Glorified and exalted is He above all what they associate with Him!} [Surat az-Zumar: 67] [Narrated by Al-Bukhāri (4811), Muslim (2786), and At-Tirmidhi (3238)]
We believe that people will be resurrected from their graves. Allah Almighty will bring life back to the dead upon the second blow of the trumpet. Then, they will stand before the Lord of all the worlds. Allah, Glorified be He, says: {Then after that you will surely die, then on the Day of Resurrection you will surely be resurrected.} [Surat al-Mu’minūn: 15-16] Allah Almighty also says: {The Trumpet will be blown [again], and at once they will rush from their graves to their Lord. They will say: "Woe to us! Who has resurrected us from our resting place?" [They will be told]: "This is what the Most Compassionate promised, and the messengers told the truth." It will only be a single Blast, and at once they will all be brought before Us.} [Surat Yāsīn: 51-53]
And He, Glorified be He, says: {Indeed, it is We Who give life and cause death, and We are the Inheritors [of all things]. We surely know those of you who have gone before and those who are yet to come. It is your Lord Who will gather them together. He is All-Wise, All-Knowing.} [Surat al-Hijr: 23-25]
In another verse, He Almighty says: {They say: "What! When we are turned into bones and dust, will we really be resurrected as a new creation?" Say: "Be you stones or iron, or any other substance you think is harder to bring back to life." They will then say: "Who will bring us back [to life]?" Say: "The One Who created you the first time." They will shake their heads at you and say: "When will that be?" Say: "Perhaps it is soon." On the Day when He calls you, you will respond by praising Him, thinking that you had not stayed [on earth] except for a little while.} [Surat al-Isrā’: 49-52] Allah Almighty also says: {Whoever Allah guides is truly guided; and whoever He causes to stray, you will find none to protect them besides Him. On the Day of Resurrection, We will gather [and drag] them on their faces – deaf, dumb and blind. Their abode will be Hell; every time it subsides, We will flare it up for them. That will be their recompense because they rejected Our verses and said: "What! When we are turned into bones and crumbled particles, will we really be raised as a new creation?" Do they not see that Allah, Who created the heavens and earth, is able to create the like of them? He has decreed for them an appointed time, about which there is no doubt, yet the wrongdoers persist in denial.} [Surat al-Isrā’: 97-99] And Allah, the Exalted, says: {But when the promise of the Hereafter comes, We will bring you all together.} [Surat al-Isrā’: 104] Too numerous are the verses that affirm the Resurrection.
We believe that Prophet Muhammad (may Allah's peace and blessings be upon him) will be the first one to come out of the grave. Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "I will be the chief of the children of Adam on the Day of Judgment, the first one for whom the grave will be split open, and the first intercessor and the first one whose intercession will be accepted." [Narrated by Muslim (2278) and Abu Dāwūd (4673)]
The first one to regain his consciousness will be the Prophet (may Allah's peace and blessings be upon him). In a Hadīth, he said: "Do not give me preference over Mūsa, for the people will fall unconscious on the Day of Resurrection and I will be the first to regain consciousness, and behold! Mūsa will be there holding the side of Allah's Throne. I will not know whether Mūsa has been among those people who have become unconscious and then has regained consciousness before me, or has been among those exempted by Allah from falling unconscious." [Narrated by Al-Bukhāri (2441) and Muslim (2373)]
The first one to be clothed will be Prophet Ibrāhīm (peace be upon him). The Prophet (may Allah's peace and blessings be upon him) said: "The first one to be clothed on the Day of Judgment will be Ibrāhīm." [Narrated by Al-Bukhāri (3349), Muslim (2860), At-Tirmidhi (2423), and An-Nasā'i (2082)]
People will be resurrected barefooted, naked, and uncircumcised. The Prophet (may Allah's peace and blessings be upon him) said: "People will be resurrected on the Day of Judgment, barefooted, naked, and uncircumcised." [Narrated by Al-Bukhāri (6527), Muslim (2859), An-Nasā’i (2083), and Ibn Mājah (4276)]
We believe that the earth on which people will be resurrected is different from this earth. Allah, the Exalted, says: {The Day when the earth will be changed to another earth and so will the heavens, and all will appear before Allah, the One, the Subjugator.} [Surat Ibrāhīm: 48]
The land of resurrection will be white. The Prophet (may Allah's peace and blessings be upon him) said: "The people will be resurrected on the Day of Resurrection on a white land with a reddish tinge like the loaf of white bread." [Narrated by Al-Bukhāri (6521) and Muslim (2790)]
Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "The earth will turn to be a single bread on the Day of Resurrection and the Almighty Lord will turn it in His Hand as one of you turns a loaf while on a journey." [Narrated by Al-Bukhāri (6520) and Muslim (2792)]
As to where humankind will be as the earth will turn into another one and the heavens too, there are authentic Hadīths that tell about that. Thawbān, the Prophet's freed slave, reported: A Jewish rabbi came to the Messenger of Allah (may Allah's peace and blessings be upon him) and said: "Where will the human beings be on the Day when the earth will change into another earth and the heavens too?" The Messenger of Allah (may Allah's peace and blessings be upon him) said: "They will be in darkness beside the Bridge." [Narrated by Muslim (315)]
‘Ā’ishah (may Allah be pleased with her) reported: I ask the Messenger of Allah (may Allah's peace and blessings be upon him) about the verse that reads: {The Day when the earth will be changed to another earth and so will the heavens} [Surat Ibrāhīm: 48], as to where the people will be on that Day, O Messenger of Allah? He said: "On the Sirāt (the Bridge)." [Narrated by Muslim (2791)]
We know that this Day is a very momentous one. Allah Almighty says: {Do they really not think that they will be resurrected for a momentous Day?} [Surat al-Mutaffifīn: 4-5] He Almighty also says: {O mankind, fear your Lord; the earthquake of the Hour is something dreadful.} [Surat al-Hajj: 1]
It equals fifty thousand years, as authentically reported. Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "No owner of a treasure who does not pay Zakah... until Allah pronounces judgment among His servants, during a Day the extent of which is fifty thousand years by your measure, and he will see his path leading either to Paradise or to Hellfire." [Narrated by Al-Bukhāri (2371), Muslim (987), Abu Dāwūd (1658), At-Tirmidhi (1636), An-Nasā’i (3563), and Ibn Mājah (2788)]
On that Day, the sun will draw close to the earth. Abu ’Umāmah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "On the Day of Resurrection, the sun will draw so close to the people that there will be left only a distance of one mile." Sulaym ibn ‘Āmir said: "By Allah, I do not know whether he meant by 'mile' the mile of the earth or an instrument used for applying kohl to the eye." He said: "The people will be submerged in perspiration according to their deeds, some up to their knees, some up to their waist, and some will be totally bridled by perspiration." [Narrated by Muslim (2864) and At-Tirmidhi (2421)]
The believers will be shielded from the heat of the sun by virtue of their good deeds. Some will be covered by the shade of the Throne, as related in a Hadīth that reads: "There are seven types of people whom Allah will cover in His shade on a Day there will be no shade but His shade." [Narrated by Al-Bukhāri (660) and Muslim (1031)]
Some will be shaded by Surat al-Baqarah and Surat Āl ‘Imrān, which will plead for those who recite them. The Prophet (may Allah's peace and blessings be upon him) said: "Recite the Qur’an, for on the Day of Resurrection it will come as an intercessor for those who recite It. Recite the two bright ones, Al-Baqarah and Āl ‘Imrān, for on the Day of Resurrection they will come as two clouds or two shades, or two flocks of birds in ranks, pleading for those who recite them. Recite Surat al-Baqarah, for taking recourse to it is a blessing and abandoning it is a cause of grief, and magicians cannot confront it." [Narrated by Muslim (804)] Some will be shaded by the shade of their truthfulness. The Prophet (may Allah's peace and blessings be upon him) said: "Everyone will be in the shade of his truthfulness until judgment is passed among people." [Narrated by Ahmad (17333), Abu Ya‘la (1766), Ibn Khuzaymah (2431), Ibn Hibbān (3310); classified as Sahīh (Authentic) by Ibn Khuzaymah and Ibn Hibbān]
