Kashmirigirl, I think you must have heard about Dajjal (Antichrist) some place. I am attaching few hadiths from Sahih Bukhari and Sahih Muslim.
From Sahih Muslim (kitab Al-Fitan Wa Ashrat As-Sa'Ah)

Book 40, Number 7015:
Narrated An-Nawwas ibn Sam'an:
Allah's Apostle (peace_be_upon_him) mentioned of the Dajjal one day in the morning. He sometimes described him as
insignificant and sometimes described (his turmoil) as very significant (and we felt) as if he were in the cluster of the
date-palm trees. When we went to him (to the Holy Prophet) in the evening and he read (the signs of fear) on our faces,
he said: What is the matter with you? We said: Allah's Apostle (peace_be_upon_him) you mentioned the Dajjal this
morning (sometimes describing him) as insignificant and sometimes very important, until we began to think he was
present in some (nearly) part of the cluster of the date-palm trees.
So he said: I harbour fear in regard to you in so many other things besides the Dajjal. If he comes forth while I am among
you, I shall contend with him on your behalf, but if he comes forth while I am not among you, a man must contend on his
own behalf and Allah will take care of every Muslim on my behalf (and safeguard him against his evil). He (the Dajjal) will
be a young man with twisted, cropped hair, and a blind eye. I compare him with AbdulUzza ibn Qatan. He who among
you will survive to see him should recite over him the opening verses of Surah al-Kahf (xviii). He will appear on the way
between Syria and Iraq and will spread mischief right and left. O servant of Allah! Adhere (to the path of Truth).
We said: Allah's Apostle (peace_be_upon_him), how long will he stay on Earth? He said: For forty days, one day like a
year, one day like a month, one day like a week, and the rest of the days will be like your days. We said: Allah's Apostle
(peace_be_upon_him) will one day's prayer suffice for the prayers of the day equal to one year? Thereupon he said: No,
but you must make an estimate of the time (and then observe prayer).
We said: Allah's apostle (peace_be_upon_him) how quickly will he walk upon the earth? Thereupon he said: Like cloud
driven by the wind. He will come to the people and invite them (to a wrong religion); they will affirm their faith in him and
respond to him. He will then give a command to the sky: there will be rainfall upon the Earth and it will grow crops. Then
in the evening, their pasturing animals will come to them with their humps very high, their udders full of milk and their
flanks distended. He will then come to another people and invite them. But they will reject him so he will go away from
them; they will have a drought and nothing will be left with them in the form of wealth.
He will then walk through the desert and say to it: Bring forth your treasures. The treasures will come out and gather
before him like a swarm of bees. He will then call someone in the flush of youth, strike him with the sword, cut him into
two pieces and (make these pieces lie at the distance which is generally between the archer and his target.
He will then call (that young man) and he will come forward laughing with his face gleaming (with happiness). It will at this
very time that Allah will send Christ, son of Mary.............

[For the sake of space I have quoted the first half of hadith]
Here are few more hadiths from Sahih Bukhari

Volume 9, Book 88, Number 241:
Narrated Abdullah bin Umar:
Allah's Apostle stood up amongst the people and then praised and glorified Allah as He deserved and then he
mentioned Ad-Dajjal, saying, "I warn you of him, and there was no prophet but warned his followers of him; but I will tell
you something about him which no prophet has told his followers: Ad-Dajjal is one-eyed whereas Allah is not."
[/quote]
[Why do you think, the Prophet felt the need to make that last distinction (about the one eye). Dajjal 'll have powers to fool someone not careful enough, from the path of Allah... whether these powers are all uh.. metaphors, is something I don't have enough knowledge to talk about]

Volume 9, Book 88, Number 243:
Narrated 'Aisha:
I heard Allah's Apostle in his prayer, seeking refuge with Allah from the afflictions of Ad-Dajjal.

Volume 9, Book 88, Number 246:
Narrated Abu Sa'id:
One day Allah's Apostle narrated to us a long narration about Ad-Dajjal and among the things he narrated to us, was:
"Ad-Dajjal will come, and he will be forbidden to enter the mountain passes of Medina. He will encamp in one of the salt
areas neighboring Medina and there will appear to him a man who will be the best or one of the best of the people. He
will say 'I testify that you are Ad-Dajjal whose story Allah's Apostle has told us.' Ad-Dajjal will say (to his audience),
'Look, if I kill this man and then give him life, will you have any doubt about my claim?' They will reply, 'No,' Then
Ad-Dajjal will kill that man and then will make him alive. The man will say, 'By Allah, now I recognize you more than ever!'
Ad-Dajjal will then try to kill him (again) but he will not be given the power to do so."
[/quote]
[Note the last part, "not be given the power to do so".]

Volume 9, Book 88, Number 245:
Narrated Anas:
The Prophet said, "No prophet was sent but that he warned his followers against the one-eyed liar (Ad-Dajjal). Beware!
He is blind in one eye, and your Lord is not so, and there will be written between his (Ad-Dajjal's) eyes (the word) Kafir
(i.e., disbeliever)." (This Hadith is also quoted by Abu Huraira and Ibn 'Abbas).
