many peopple have accepted him as such. please beware as it's possible he won't come out with the name dajjal at the start. a lot of times, the difficulties imposed on the muslims by the kafirs is what causes a person to sacrifice their belief, and so fall into the dajjal trap.
The word "Dajjal" is an epithet. It means "The Deceiver" or "The Great Liar". If someone wanted to be known literally as God Himself, then he would not say he is a liar for his name. There are also thirty other Dajjals, but no one mentions them being named Dajjal as well. This biggest Dajjal does not necessarily have to be qualified as the biggest Dajjal by being named so. Think about it. To say so is like saying you know for sure. But only Allah knows best.
You clearly mentioned one of the signs of Dajjal, and I believe you have truly kept your eyes open:
there is a hadith that the dajjal will enter one village and tell the inhabitants to accept him. when they refuse, the dajjal will go through this farms, and their crops will become yellow and their cattle will become thin and won't have milk. on the other hand, in another village, the people will accept the dajjal, and their crops will become better and their animals fatter and more milk-producing. (summary of hadith in my own words)
There are so many other reasons why today the signs in the Ahadith are fulfilled in a manner of speaking, since the Western governments learned how to make it rain by their command, using cloud seeding techniques. They are researching on how to make it rain by pointing lasers at the sky! If that isn't making it rain by command, I don't know what it is.
They also use hormones to make cattle produce much greater yields of milk than ever before. They patented seed life, such as the Monsanto company, and they protect their own crops and those who grow their crops with fertilizers and chemicals, but these chemicals cause the destruction of life surrounding them and other people's crops are destroyed. So is their health damaged in many ways. This is all very deceitfully done as well. Companies hide the problems they create and deny them through manipulating the system.
People are "revived" from the brink of death these days with modern medicine, by being cut in half on the surgery table, then sown back whole. Such people are thus "revived" and gleam with happiness. The deceit behind this is that many people today attribute the miracle of surviving a sickness to modern science, and forget God altogether thinking that human knowledge and progress is the defining factor which saved them, while Allah has power over all things. That is like attributing divinity to where it does not belong.
Modern technology has allowed the West to mine oil in the waste lands and use that oil and mineral wealth for their own countries, leaving the Third World nations to suffer the plight of pollution and other negative effects. These same people have used these means to travel around the world like a cloud driven by the wind (the airplanes, which have jet engines sucking in air and expelling it out through the back, thus it is driven by the wind itself since it uses it for propulsion).
It is said he could revive people's family members and animals from the dead. If you think about it, cloning technology is progressing for past animals to be revived from the dead. The Dolly sheep was the first attempt at this new cloning technology in 1997. These signs just keep appearing. Is it any coincidence? Let's look at others:
It is said that he will have music which the music lovers will be attracted to, and we see that with the Western nations mostly. The whole world has been traveled by our current age, and beyond. A day experienced by someone who travels to the Arctic and Antarctic regions lasts a full day, and if one heads from the poles to the equator, the days shorten in length until they become like our normal days in length.
Now, the Arctic region is slowly becoming warmer and thus more habitable in the future. There are disputes concerning its territory. It is the last frontier in exploration on earth. This was only possible with greenhouse gases like in the world today, produced by the very same nations that use technology using the wealth from beneath the earth.
Apparently, one of the meanings of the word Dajjal is one who travels the world for commercial exploits. This is exactly what we see today.
Coincidence? I think not.
