Write five major signs of dooms day (day of judgment) in the light of ahadees e sahehah

Ibn Umar reported: The Messenger of Allah, peace be upon him, turned to us and said, ”O emigrants, there are five things with which you will be tested, and I seek refuge with Allah lest you live to see them:

1.      Sexual immorality never appear among people to such an extent that they commit it openly except that they will be afflicted by plagues and disease (e.g. AIDS and etc ) unknown to their forefathers;

2.      They do not cheat in weights and measures(business, trades, etc) except that will be stricken with famine, calamity, and the oppression of rules;

3.   They do not withhold charity from their wealth except that rain will be withheld from the sky, and were it not for the animals there would be no rain at all;

4.   They do not break their covenant with Allah and His Messenger except Allah will enable their enemies to overpower them and take some of what is in their hands;

5.   And unless their leaders rules according to the Book of Allah and seek every good from that which Allah has revealed, then Allah will cause them to fight one another.”

[Sunan ibn Majah, Book of trials, Number 4019 Sahih]

Abdullah ibn Amr reported: The Messenger of Allah, peace be upon him, said, “The hour will not be established until people fornicate with each other in the road just as a donkey fornicate.[1]”

[Ref: Saheeh ibn Hibban 6767; Musnad Bazzar 3408; saheeh according to the jumhoor Muhadditheen]

1. Mahdi will arriveIt was asserted in hadith:
(Before Doomsday, Allah will create one of my descendants, whose name and father’s name will be the alike as those of mine. The land, which will have been loaded with evil before him, will be charged with equity during his time.) [Tirmidhi](There will be a cloud just over Mahdi’s head. An angel from the cloud will say, “This is Mahdi. Regard what he says.”) [Abu Nu’aym]
2. Dajjal will arrive

It was said in a hadith:

(Dajjal will emerge and will claim that he is a god. He who believes in his divinity will be a disbeliever.) [Ibn Abi Shayba]
3. Jesus will descend from the sky

It is revealed in the Qur’an al-Karim:

(We cursed Jews because of their saying, “We murdered ‘Isa, son of Maryam, the Messenger of Allah.” They did not murder him, nor did they crucify him. The murdered one was made to appear to them like ‘Isa.) [Surat-un-Nisa’ 157]‘Isa has been raised to the sky. (Surat-un-Nisa’ 158)‘Isa’s descending from the sky in the time period close to Doomsday is surely knowledge which shows the approach of Doomsday. Have no doubt about it.) [Surat-uz-Zukhruf 61, Baydawi]
Also, it is stated in hadith:
(‘Isa will descend from the sky as a just judge. He will break the cross [he will wipe out Christianity], kill pigs [he will forbid pork], and prohibit everything other than Islam.) [Bukhari, Muslim, Abu Dawud, Tirmidhi, Ibn Abi Shayba](With the descent of ‘Isa, peace and security will prevail everywhere so much so that lambs will wander with wolves freely; children will play with snakes.) [Abu Dawud](Doomsday will not come before 10 presages appear. One of them is ‘Isa’s descent from the sky.) [Muslim, Abu Dawud, Tirmidhi, Ibn Maja, Nasai, Imam-i Ahmad, Tabarani, Ibn Hibban, Ibn Jarir]
4. Dabbat-ul-ard will rise
(Dabbat-ul-and will touch a Believer with the staff of Musa. Then “He is destined for Paradise” will be written on his forehead, and his face will glitter. It will hit a disbeliever with the seal of Sulaiman. Then “He is destined for Hell” will be written on his forehead, and his face will blacken.) [Tirmidhi]The Qur’an al-Karim, too, makes a reference to this beast. (Surat-un-Naml 82)
5. Gog and Magog will riseIt is revealed in the Qur’an:(The wall will collapse; Gog and Magog will rush down from every hill.) [Surat-ul-Anbiya 96]
It is declared in a hadith:(Gog and Magog are one of the first signs of Doomsday.) [Ibn Jarir]
