Abu Huraira reported Allah's Messenger صلى الله عليه وسلم as saying: "The Last Hour will not come until the Muslims fight against the Jews and the Muslims kill them to the extent that the Jews will hide behind a rock or a tree and the rock or the tree will say: O' Muslim, the servant of Allah, there is a Jew behind me; come and kill him; but the Gharqad tree ( Boxthorn tree) will not say that because it is the tree of the Jews." (Sahih Muslim) The Jews are currently planting lots of Gharqad trees in Israel to protect them.
Well, this hadith is about the end of Times and there is no " o Abdullah ".
As muslims, we think that when the Times will come the Antechrist ( we call him al Massih al Dajjal ) will come on and try to convinced people that he is God but of course that he is not but God will give them abilities as killing people and them bring them back to life or ordonning to Djinns to take the appearance of deceaded people to convinced them that he must be worshipped and he will try to get worshippers.
He will come in every city exept Mecqua and Medina and he will see every humain beeing in 40 days. This will be the worst trial for humanity in islam.
He will arrived in a city where muslims will take refuge the city of QOUM ( we don't really know which city it's represent ). He will get around the city with his army of worshippers and he will try to enter to kill them but the city have like a wall all around so they could not enter.
Then on the city of Damascus we think the the Prophet Isa ( Jesus ) pbuh will come back to Earth and he will go to the city of Qoum to help the muslims. He will arrived for the time of the prayer of the morning and the imam will not regonized this man.
This imam is the imam of the end of Time imam al Mahdiand he will be in a community of 1200 muslims ( the number of muslims at time period ) so he will know everybody.
When he will see Isa pbuh he will know who he is and he will know that he is imam al Mahdi. He will let him the place to lead the prayer but Isa pbuh will refused and will pray in the row as every other muslim.
After the prayer he will ask to open the doors to face al Dajjal and his army. When the fake Messiah will see the real Messiah he will run away but Isa pbuh will catch him up and kill him with his swords.
Then he will kill his followers to retablish the real religion of God. As we know, the Jews are waiting for their Messiah to come. So they will all follow al Dajjal.That's why he will kill the Jews and the rocks and trees will talk to inform Isa pbuh of where they are hiding so he could kill them all for disbeliving in God all Powerful.
Abu Huraira narrated that Prophet Mohammad صلى الله عليه وسلم said: "There is no prophet between me and him (Jesus Christ عليه السلام ). He shall descend so, recognize him when you see him. He is a man of medium height, (his complexion) is between reddish and white; he will be between (or dressed in) two slightly yellowish garments; His head looks as if it is dripping water even though it is not wet. He will fight people in the cause (for the sake) of Islam, will break the Cross and kill the swine (pig) and abolish Jizya (tax on Christians and Jews); and Allah will put an end to all religious sects except Islam during his (Jesus') time. He (Jesus) will slay the Antichrist (Dajjal) and he will stay in the World for 40 years. Then, he will die and the Muslims will perform the funeral prayer for him." (Abu Dawud and Musnad Ahmad)
