Note: Rasulullah (Sallallahu Alayhi Wassallam) has exhorted the regular recital of Suratul Kahf which will most certainly save one from the Evils of Dajjal.
Hadhrat Imraan bin Husain (R.A.) relates that, "I heard Rasulullah (Salallahu Alayhi Wasallam) saying: "Since the birth of Adam (A.S.) till the advent of Qiyamah there is no fitnah (evil, test) much greater that of Dajjal."
Hadhrat Huzaifah (R.A.) says, Dajjal will be blind in his left eye. He will have very thick hair on his body and he will also have his own type of Jannat (Heaven) and Jahannam (Hell) with him: Although his Jannat will appear as Jannat, in reality it will be Jahannam and likewise though his Jahannam will appear to be Jahannam, in reality it will be Jannat.
Imraan bin Husain (R.A.) says Rasulullah (Salallahu Alayhi Wasallam) said: "Those who hear about Dajjal should stay far from him. By Allah! A person will approach him thinking him to be a Believer, but on seeing his amazing feats he will become his follower."
Ubadah bin Saamit (R.A.) once said, "I have explained Dajjal to you but I fear that you might not have understood. Maseeh Dajjal will be short, and his legs will be crooked. The hair on his head will be extremely twisted. He will have one eye (with which he can see, and this is the protruding eye about which other ahadeeth inform us) while his other eye will be totally flat. It will neither be deep (in its socket) nor protruding.
If you still have any doubt regarding him then remember that your Sustainer (Rabb) is not one-eyed. (Because Dajjal will eventually claim to be Allah). In a lengthy Hadith narrated by Abu Saeed (R.A.), Rasulullah (Salallahu Alayhi Wasallam) is reported to have said: "Dajjal will come but it will be prohibited and impossible for him to enter Madina. He will set up camp in a barren land outside Madina. One person who will be the best of persons will confront him by saying: "I bear witness that you are the very Dajjal about whom Rasulullah (Salallahu Alayhi Wasallam) has informed us."
Dajjal will say to his followers, "If I kill this person and then revive him, you people will still doubt me?"
They will reply, "No."
He will then kill this person, (according to another narration he will split this person in two) and thereafter revive him. This person will say, "I am totally convinced more than ever before that you definitely are Dajjal."
Dajjal will attempt to kill this person again but his efforts will now be in vain.
(According to a hadith, after this incident, Dajjal will not be able to harm anyone.)
Hadhrat Anas (R.A.) says that Rasulullah (Salallahu Alayhi Wasallam) said: "Dajjal will come and finally reach the outskirts of Madina. There will be three tremors. At that time, all the disbelievers and hypocrites will flee (from Madina).
In this way Madina Munawwarah will be purified of all the evil hypocrites.
Hadhrat Asma bint Yazeed (R.A.) narrates that Rasulullah (Salallahu Alayhi Wasallam) once came to my house and there he spoke about Dajjal. He said that before the emergence of Dajjal there will be three spells of drought. In one year the skies will withold one third of its rains, causing the earth to withold one third of its produce. In the second year the skies will withold two thirds of its rains, causing the earth to withold two thirds of its produce. In the third year, the skies will withold all its water and there will be no crops that year. All animals, be they hooved or toothed, will die as a result. The greatest evil of Dajjall will be to approach anyone and ask him: "If I bring your camel back to life, will you then believe that I am your Rabb?"
This person will reply, "Most certainly."
Thereafter Shaytaan (from the many Shayateen who will always accompany Dajjal) will appear before this person in the form of his camel with a fat hump and fully laden udders.
Likewise Dajjal will appear before another person whose father and brother have long passed away and ask him, "If I bring your father and brother back to life will you believe that I am your Rabb?"
This person will reply, "Why not?"
Shaytaan will once again take on the appearance of his brother and father...
Hadhrat Mughira ibn Shu'ba (R.A.) says that, "No one asked Rasulullah (Sallallahu Alayhi Wassallam) about Dajjal as much as myself. Rasulullah (Sallallahu Alayhi Wassallam) said to me, "How can he possibly harm you?"
I said: "People are saying that he will have with him a mountain of bread (provisions) and a river of water."
Rasulullah (Sallallahu Alayhi Wassallam) said: "In the sight of Allah he is much more disgraced than that. (i.e. Allah knows full well that in reality Dajjal has nothing with him, and all that which appears to be with him is but deception). (Bukhari and Muslim).
Other Ahadeeth regarding Dajjal inform us that:
He will emerge between Shaam and Iraq, and his emergence will become known when he is in Isfahaan at a place called Yahudea.
The Yahudis (Jews) of Isfahaan will be his main followers.
Apart from having mainly Yahudi followers, he will have a great number of women followers as well.
He will have with him fire and water, but in reality the fire will be cold water while that what appears to be cold water will in reality be a blazing fire.
Those who obey him will enter "his Jannat" while those who disobey him will enter "his Jahannam."
There will be a thick fingernail-like object in his left eye.
The letters "Kaa" "Faa" "Raa" will appear on his forehead and will be deciphered by all Mu'mineen regardless of them being literate or not.
He will have a wheatish complexion.
He will travel at great speeds and his means of conveyance will be a gigantic mule. It is said that he will play beautiful music which will attract the music lovers.
Dajjal will lay claim to prophethood.
He will then lay claim to Divinity.
He will perform unusual feats.
He will travel the entire world. He will send down rains upon those who believe in him, which in turn will cause good crops to grow, trees to bear fruit and cattle to grow fat.
He will cause drought to those who disbelieve in him, resulting in starvation and hardship for them.
During those trying times the Mu'mineen will satiate their hunger through the recitation of Subhanallah and La'ilaha Ilallahu.
The hidden treasures will spill forth at his command. He will stay on this Earth for a period of forty days; the length of the first day will be one year, the second day will be equal to one month, the third day will be equal to a week and the remaining days will be normal.
He will be unable to enter Makkah because the Malaikah will be guarding the Holy City and nor will he be able to enter Madina because there will be Malaikah guarding each of the seven entrances to Madina; From Madina he will proceed towards Shaam where Imaam Mahdi will be stationed.
Finally Isa (A.S.) will descend from the heavens and pursue him and eventually kill him at present day Lydda (Baad Lud).
