Dajjal

Dajjal aka the Anti-Christ or False Messiah is a Jinni, not a human; a soldier of Satan, chained in shackles. During mankind’s last hour on the earth, he will be released for humankind’s last and final test. After 40 years of rule, Prophet Isa (Jesus Christ) will kill him.

"And they had a king over them, which is the messenger of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon." - Revelation 9:11

Narrated 'Abdullah bin 'Umar: Allah's Apostle said. "While I was sleeping, I saw myself (in a dream) performing Tawaf around the Ka'ba. Behold, I saw a reddish-white man with lank hair, and water was dropping from his head. I asked, "Who is this?' They replied, 'The son of Mary.' Then I turned my face to see another man with a huge body, red complexion and curly hair and blind in one eye. His eye looked like a protruding out grape. They said (to me), he is Ad-Dajjal." The Prophet added, "The man he resembled most is Ibn Qatan, a man from the tribe of Khuza'a." - al-Bukhari Sahih al-Bukhari Sahih al-Bukhari, 9:88:242

Narrated Ibn Umar: Once Allah's Apostle stood amongst the people, glorified and praised Allah as He deserved. Then, mentioning Dajjal, he said, "I warn you against him (i.e. the Dajjal) and there was no prophet but warned his nation against him. No doubt, Noah warned his nation against him but I tell you about him something of which no prophet told his nation before me. You should know that he is one-eyed, and Allah is not one-eyed." - al-Bukhari Sahih al-Bukhari Sahih al-Bukhari, 4:55:553
