Dajjal

There is no creature from the creation of Adam(A.S) until the establishment of the Hour that is greater than the Dajjal. Every Prophet warned his followers about him. Hazrat Muhammad (PBUH)used to seek refuge with Allah from him in every prayer (Salah). The Prophet also used to mention him often to his Companions All of this will happen by the Decree of Allah and His Will. Then, after all of this, Allah will remove his abilities to do these things, and he will not be able to kill that man whom he had resurrected after he had killed him, nor anyone else. Allah will test His servants with him towards the end of time. Allah will misguide many people by him and guide many others by him as well. The people who have doubts will disbelieve and those who believe will increase in their Faith.

The Dajjal will stay for 40 Days

The Dajjal's stay on the earth will be for forty days, during which one day will be like a year, one day like a month, one day like a week, and then the rest of the days will be like the rest of our normal days. His speed in traversing through the land will be like rain that is driven by a strong wind. The Dajjdl will appear from the East. People will flee from him into the mountains, and he will travel throughout the earth.

The Dajjdl will not be able to enter Makkah and Al-Madinah
The Dajjdl will not leave any land except that he will enter it, except for Makkah and Al- Madinah.

For verily Allah has forbidden him from entering them. Every time he tries to enter them he will be met by an angel who will be carrying an unsheathed sword in his hand. This angel will prevent him from entering these two cities. There will be angels guarding every path that leads to these two cities.
He will be a large bodied, young, white man, with a distinctly protruding forehead and a broad chest. He will have a lot of curly hair on his head and will be blind in one eye. His eye that is not blind will look like a floating grape. He will not have any children.
He will be the largest and strongest man that we have ever seen. He will have written between his eyes the word Kafir . Every believer will be able to read this whether he is literate or not.

Dajjal is a human being who eats and drinks and Allah is far above these needs. The Dajjal is blind in one eye and Allah is not blind. No one will see Allah before death, but the people will see the Dajjal.

Indeed the protection from the Dajjdl is attained by adherence to Islam and arming oneself with Islam. One should know the Names of Allah and His Perfect Attributes in light of what has been reported in the Book of Allah the Qur'an and the Sunnah of His Messenger .

If you hear about the Dajjdl his appearance in the land then you should avoid him and not go to him. For verily a man will go to him who will be considered a believer, but will end up following him because of what he has been sent with of doubtful matters (i.e., things that cause doubt in a person's Faith.

When the Dajjdl appears at the end of time, his followers will be numerous and his evil will be widespread.

Imam As-Safareeni

No one will be saved from him except a small number of the believers. At that time Hazrat Eisa (A.S) will descend in the eastern part of Damascus at the place of the white minaret. The believing servants of Allah will gather around him and he will go with them kills the Dajjdl

A man who will go to him who will be considered a believer, but will end up following him because of what he has been sent with of doubtful matters .

When the Dajjal appears at the end of time, his followers will be numerous and his evil will be widespread. No one will be saved from him except a small number of the believers. At that time Hazrat Eisa (A.S) will descend in the eastern part of Damascus at the place of the white minaret.
At the time of 'Hazrat Eisa (A.S)'s descent, the Dajjdl will be heading towards Jerusalem and Hazrat Eisa (A.S) will meet him at the gate of Ludd in Palestine. When the Dajjdl sees Hazrat Eisa (A.S) he will
begin to melt like salt melts in water. Then Hazrat Eisa (A.S) will say to him: "Verily, I have one blow to give you that I will never miss!" ' Hazrat Eisa (A.S) will then catch him after the Dajjal tries to flee and kill him with his spear, and his followers will be defeated. The believers will pursue them and kill them. With his death the great trial will come to an end and all matters belong to Allah both before and after.
The time of Hazrat Eisa (A.S) after the killing of the Dajjal, will be a time of ease, pleasure and comfortable living. Allah will send a rain that will fall upon every house, whether it is a city dwelling or a rural dwelling. It will be said to the earth: "Bring forth your vegetation and pour forth your blessings." So on that day, a large group of people will eat from one pomegranate and then they will seek shade under its huge peel. They will also be blessed in their milking of animals so much so that the milk of camels will suffice a large number of people, and the milk of cows will suffice a tribe of people, and the milk of sheep will suffice a section of a tribe of people. Tranquility and peace will cover the earth. The dangerous animals will roam freely with the grazing camels, tigers will mingle freely with cattle, and wolves will roam freely with sheep. The children will be able to play with snakes, and the snakes will not harm them.

Cool Breeze from the direction of Syria

Hazrat Eisa (A.S) will remain on earth for seven years. Allah will then send a cool breeze from the direction of Syria (Ash-Sham). This breeze will not leave upon the face of the earth anyone in whose heart there will be even an atom's weight of good or Faith, except that it will cause him to die. After this, the Hour will be established and there will not remain on the face of the earth anyone who says, "Allah, Allah."

The Sun will rise from the West

The sun will rise from its setting place in the west and when it does so, the people will see it and all will believe (in Allah). But that will be a time when no person's Faith will benefit him who did not believe before, or earn any good
Hadith
One companion of The Holy Prophet (PBUH) tells that He (PBUH) used to mention him so much that we thought that he was hiding in a group of date-palm trees . So we went to the one evening and when he recognized that (fear) in us he said:
"What's the matter with you all?"
We replied: "O Messenger of Allah! You mentioned the Dajjdl to us this morning and you raised and lowered your voice so much concerning him that we thought that may be he is hiding amongst the date-palm trees (nearby)." The Holy Prophet (PBUH)
"I do not fear for you concerning the Dajjdl. If he appears while I am amongst you all, then I will protect you from him. However, if he appears and I am not amongst you all, then every man must protect himself. And Allah will look after the affair of every Muslim after me."
