According to Quran and Sunnah
Conquest of Constantinople
Hadith – Abu Dawood #4283, Narrated Abdullah ibn Busr
The Prophet said: The time between the great war and the conquest of the city (Constantinople) will be six years, and the Dajjal (Antichrist) will come forth in the seventh.
Hadith – Abu Dawood #4282, Narrated Mu’adh ibn Jabal
The Prophet said: The greatest war, the conquest of Constantinople and the coming forth of the Dajjal (Antichrist) will take place within a period of seven months.
Reward from Allah for being the Dajjal’s enemy
Hadith – Abu Dawood #4232, Narrated Hudhayfah ibn al-Yaman
Then the Antichrist (Dajjal) will come forth accompanied by a river and fire. He who falls into his fire will certainly receive his reward, and have his load taken off him, but he who falls into his river will have his load retained and his reward taken off him. I then asked: What will come next? He said: The Last Hour will come.
Protection from the Trial of the Dajjal
Hadith – Al-Tirmidhi #2146, Narrated AbudDarda’
Allah’s Messenger said, “He who recites three verses at the beginning of al-Kahf will be protected from the trial of the Dajjal.“
[Tirmidhi transmitted it, saying this is a hasan sahih tradition.]
Hadith – Muslim #7034, Narrated Anas ibn Malik
Allah’s Apostle said: The Dajjal would be followed by seventy thousand Jews of Isfahan wearing Persian shawls.
Hadith – Muslim #7025, Narrated Abdullah ibn Amr ibn al-‘As
I committed to memory a hadith from Allah’s Apostle and I did not forget it after I had heard Allah’s Apostle said: The first sign (out of the signs of the appearance of the Dajjal) would be the appearance of the sun from the west, the appearance of the beast before the people in the forenoon and which of the two happens first, the second one would follow immediately after that.
Dajjal will Perish
Hadith – Muslim #3187, Narrated AbuHurayrah
Allah’s Messenger said: Dajjal will come from the eastern side with the intention of attacking Medina until he will get down behind Uhud. Then the angels will turn his face towards Syria and there he will perish.
Hadith – Muslim #6924, Narrated AbuHurayrah
Allah’s Apostle said: The Last Hour will not come until the Romans land at al-A’maq or in Dabiq. An army consisting of the best (soldiers) of the people on Earth at that time will come from Medina (to oppose them). When they arrange themselves in ranks, the Romans will say: Do not stand between us and those (Muslims) who took prisoners from among us. Let us fight them. The Muslims will say: Nay, by Allah, we shall never turn aside from you and from our brethren so that you may fight them. They will then fight and a third (part) of the army, whom Allah will never forgive, will run away. A third (part of the army), which will be constituted of excellent martyrs in Allah’s eyes, would be killed. The third who will never be put on trial will win and they will be the conquerors of Constantinople. As they are busy in distributing the spoils of war (amongst themselves) after hanging their swords by the olive trees, Satan will cry: The Dajjal has taken your place among your families. They will then come out, but it will be of no avail. When they reach Syria, he will come out while they are still preparing themselves for battle, drawing up the ranks. Certainly, the time of prayer will come and then Jesus (peace be upon him), son of Mary, descend and will lead them in prayer. When the enemy of Allah see him, it will (disappear) just as salt dissolves in water and if he (Jesus) were not to confront them at all, even then it would dissolve completely. Allah would kill them by his hand and he would show them their blood on his lance (the lance of Jesus Christ).
