Al-Dajjal first appeared as the Antichrist in pseudo apocalyptic Christian literature:

Dear children, this is the last hour; and as you have heard that the antichrist is coming, even now many antichrists have come. This is how we know it is the last hour. (1 John 2:18)

Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist--denying the Father and the Son. (1 John 2:22)

but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world. (1 John 4:3)

I say this because many deceivers, who do not acknowledge Jesus Christ as coming in the flesh, have gone out into the world. Any such person is the deceiver and the antichrist. (2 John 1:7)

A lengthy hadith narrated by Ibn Majah, Ibn Khuzaymah, and Ad-Dhiya', attributed to Abu Umamah, reports that the Prophet of Allah (peace be upon him) said:
"There will be three hard years before the Dajjal (appears). During them, people will be stricken by a great famine. In the first year, Allah will command the sky to withhold a third of its rain, and the earth to withhold a third a third of its produce. In the second year, Allah will command the sky to withhold two thirds of its rain, and the earth to withhold two thirds of its produce. In the third year, Allah will command the sky to withhold all of its rain, and it will not rain a single drop of rain. He will command the earth to withhold all of its produce, and no plant will grow. All hoofed animals will perish, except that which Allah wills."

Abdullah ibn 'Umar narrated that the Messenger of Allah (peace be upon him) said:
(About Fitna in detail int the article titled: “Fitna i.e. temptation, perturbation, intrigue, disruption”) "The fitnah of al-akhlas (continuous calamity) is mass desertion and war. Then, the fitnah of assarra (meaning 'the rich', when some reach people use their money to hire others to fight for them) will start from under the feet of a man who claims that he is of me (of my descendants). However, he is not of me, for my loyal friends are the ones who have taqwa. Afterwards, people will unite around a man whose reign is unstable. Then, the fitnah of ad-duhayma (it is called 'dark and black fitnah' because of its enormity) (will start) and will not leave any member of this nation without severely touching him. When it is thought that its time has come to an end, it will be lengthened. Meanwhile (during this fitnah), a man will wake up as a believer and will meet the night as a disbeliever, until people divide into two camps; a camp of belief that contains no hypocrisy, and a camp of hypocrisy that contains no belief. If this happens, then await the Dajjal on that day or the next." (Ahmad, Abu Dawud and Al-Hakim, Mishkatul-Masabih, vol. 4, no. 5403)

There are other signs to the imminent coming of the Dajjal. Mu'adh narrated that the Messenger of Allah (peace be upon him) said:
"The flourishing of Jerusalem will mark the desertion of Yathrib (Madinah). The desertion of Yathrib will mark the start of al-malhamah (the great war that will start between Ar-Rum and the Muslim forces before Muslims conquer Constantinople for the second time). The start of al-malhamah will mark the conquering of Constantinople. The conquering of Constantinople will mark the appearance of Dajjal." (Sahih Al-Jami' as-Saghir, no. 4096)

Then, Muslims will migrate to Ash-Sham to join the Jihad against the enemies of Allah. People of Madinah will desert it, not because they dislike it, but for the purpose of joining the Jihad for the sake of Allah. Then, it will be totally uninhabited, wild animals and beasts will roam through it, and it will stay deserted until the Hour begins.

Abu Hurayrah narrated that the Messenger of Allah (peace be upon hm) said:
"They (Muslims) will leave Madinah while in its prime. Only wild beasts and birds will roam it. The last persons to be gathered (for the beginning of the Last Day) will be two shepherds from (the tribe) of Muzaynah heading towards Madinah. They will be herding their sheep, and (when they reach it) they will find it deserted. When they reach Thaniyyat al-Wada' they will collapse on their foreheads (because the Hour will have started then)." (Ahmad, Al-Bukhari and Muslim. As-Silsilah as-Sahihah, vol. 2, no. 683)

As was narrated in the hadith by An-Nawwas ibn Sam'an, the Dajjal will be killed at the hand of Jesus son of Mary.
The Dajjal's death will occur after the angels turn him towards Ash-Sham away from the outskirts of Madinah. He will perish in Ash-Sham near the eastern door of Lud in Palestine. Before we start mentioning the second coming of Jesus son of Mary, we will mention the story of Al-Mahdi, Muhammad ibn 'Abdullah. In my article titled “Who will be Mehdi” I write about him in detail.

Al-Mahdi will appear just before the coming of Jesus (peace be upon him). He will lead the Muslim nation with justice and kindness and establish Allah's rule. A righteous Caliphate will reappear after the earth has experienced its share of injustice and tyranny. Jesus son of Mary will pray behind him.

The Bible describes in a vivid language the corruption, destruction, and death typifying the end of times. We see the godly forces confronting the evil of Satan, the Antichrist, and Gog and Magog. We learn that the cataclysmic events will take place in the Middle East. But still the picture needs to be completed. Unanswered questions need to be answered. Who are Gog and Magog? Where will Jesus return? Where in the Middle East will Jesus confront the evil military forces? What nation(s) will supply the forces?

And (Jesus) shall be a Sign (for the coming of) the Hour (of Judgment): therefore have no doubt about the (Hour), but follow ye Me: this is a Straight Way. (Quran 43:61)

This is understood to refer to the second coming of Jesus in the Last Days before the Resurrection, when he will destroy the false doctrines that pass under his name, and prepare the way for the universal acceptance of Islam, the Gospel of Unity and Peace, the Straight Way of the Quran.
