Definition: Literally "The Day of Resurrection," also known as the "Day of Reckoning" or less precisely the "Day of Judgment." Islam teaches that on this Day, all living things will be raised to life again and called in front of God for the final judgment. People will be divided; some will enter Jannah (Paradise) and some will enter Jahannam (Hell-Fire).
The Qur'an describes this Day of one of happiness for the believers, and terror for those who disbelieved in its existence. The Qur'an emphasizes the power of God: "Surely, He who brings life to the dead earth (through rainfall) can surely give life to men who are dead" (Qur'an 41:39).
_______________________________________________________
None will not know exactly when the Day of Judgment will occur. However, Allah and the prophet Mohammed(S)have mentioned signs which will indicate the coming of this day.These signs are categorized into major and minor signs.
-----------------------------------------------------------------------------
Minor signs
-When it will be regarded as a shame to act on Quranic injunctions. (Abu Musa Ash'ari)
-When untrustworthy people will be regarded as trustworthy and the trustworthy will be regarded as untrustworthy. (Abu Musa Ash'ari)
-Music and musical instruments will be found in every home. (Abdullah Ibn Mas'ood)
-When violence, bloodshed and anarchy become common. (Abu Musa Ash'ari)
You shall see the barefoot, naked, shepherds compete in building tall structures. (Sahih Muslim)
-------------------------------------------------------------------------------
The major signs are those that will occur closer to the Day of Judgment, and they are said to be very extraordinary.These are the seven major signs of this day.
Major signs
1)The Appearance of Al-Maseeh-ud-Dajjal, the False Messiah. Ad-Dajjal is said to be a beast who will come claiming to be God holding heaven and hell. His sole purpose is to deceive people and lead them away from the remembrance of Allah, and the unbelievers will follow him. He will have only one good eye and he will be blind in the other eye. On his forehead there will be a sign saying "Kafir," or disbeliever. He will perform some miracles which will serve to deceive some people.
The prophet Muhammed warned,
Whoever hears about the coming of Ad-Dajjal should stay away from him because by Allah, a man could come to him thinking of himself a strong believer but then he will follow Ad-Dajjal because of the doubts he will spread[7]
There are many deceiving miracles Ad-Dajjal will perform to mislead the people on earth. He will appear between the cities of Iraq and Syria and will create disaster left and right. He will command the sky to rain and it will rain. He will command the earth, and it will produce crops. After grazing on these crops, their animals will return with their udders full of milk and their flanks stretched. When he will call people to come to a false region with him and they reject his call, he will leave them and they will suffer famine and will possess no form of wealth. Then lastly he will call a young man brimming with youth; he will strike him with a sword and cut him in two, then place the two pieces at a distance between an archer and his target. Then he will call to him, and the young man will come to him running and laughing.
At that point, Allah will send Isa, Jesus. He will search for the Ad-Dajjal and will find him at the Gate of Ludd (a city in Israel). They will engage in fierce battle and Isa will win. Then the Ad-Dajjal will be no more.
2)The Appearance of Ya'jooj and Ma'jooj: Ya'jooj and Ma'jooj are two hidden tribes of people.These tribes were disbelieving descendants of prophet Adam. They will come in enormous numbers and will outnumber all the believers of the world. They will break through a barrier that Allah created to hold them back and ravage the earth. They will drink all the water, destroy plants and animals and kill people. This will occur roughly around the time of the second coming of Prophet Isa, Jesus. Finally, Allah will send a type of worm or insect that will wipe them out.
3)The appearance of the Dabbah(the strange beast): The Dabbah is a strange beast who will have the Rod of Moses and the seal of Solomon. He will call people back to Islam. Some will heed to the call while others will reject it. The believers will then have a sign that says: "Believer" while the disbelievers will have a "Disbeliever" sign. The exact description of the animal is unknown.
4)Three Huge Earthquakes: Three major earthquakes will occur on the day of judgment and they will damage a great deal of the earth. One earthquake will occur in the east, another in the west, and the third will be in the Arabian Peninsula.
5)The Smoke: Smoke will appear all over the earth that will cause believers to catch something similar to the common cold, whereas disbelivers will be hit harder by it. Finally, a cool wind will cause all the believers to die. This all the unbelievers left on earth to experience the last hour of the day of judgment.
6)The Sun will Rise from the West: This will be a major sign indicating that the world has reached its end. Allah has created the sun and He always made it rise in the East, however, at the end of time He will reverse this process by making it rise from the West. Once this happens, Allah will not accept the repentance of the disbelievers, it will be too late for them
