The Messenger has said, "The Dajjal will be able to reach any place in the world save Makkah and Madina. Two angels will guard every entry into Madina and prevent the Dajjal from entering the holy city."-from Abu Bakr (RA) and Fatima (ra) bint Qaes-Bokhari, Muslim.
WE NEED only to take a good look around the world to understand the implication of this Hadis of the Messenger of Allah. Since the entire world along with the so-called Muslims have accepted the Dajjal's philosophy in life, manifest in democracy, socialism, monarchy and such, there is no dispute that it is universally applied and its tentacles reach into the far corners of the earth. The so-called 'Muslim' populace, their leaders and the general mass too have rejected Allah's sovereignty and traded it for that of Man, thereby adopting the Dajjali system as their own. Therefore, there is no territory it does not have access to. The only exceptions to this rule are the two holy cities of Makkah and Madina. As discussed in the previous topic, the Messenger of Allah predicted the arrival of the Dajjal in the Arabian Peninsula it self. In this one, he elaborated about the only places on earth to be immune to the Dajjal's influence. Judeo-Christian forces were invited into the Arabian Peninsula by Muslim leaders during the war in the Gulf and have remained there since, more powerful than the entire Arab world's military might put together. Yet the holy cities of Makkah and Madina have remained out of bounds for them and will continue to be so, Ensh’allah. The reason for this is not that the Arab leadership or the people can resist any attempt by the Dajjal forces to enter the holy cities, but because the Messenger of Allah has confirmed the presence of angels guarding the entrances to them. Yet, there remains a scope of argument here. These two towns, Makkah and Madina, at present are under Monarchy, which is not sovereignty of Allah and the rulers of these two towns are not Mo’men, their Elah is the Dajjal. So what is meant by these being guarded by Malayeks (angels) preventing Dajjal's entry into these two towns? In one Hadis the Messenger predicted that entire Arabia would be under the grip of Dajjal and Dajjal's influence and control will be effective there (Hadis no-XIV) and in another he said that it would be prevented from entering Makkah and Madina by Malayeks.
I think what the Messenger has meant by these two apparently contradictory Hadis is that though the Dajjal will be established over all Arabia through its rulers subservient to their dominion, but the physical presence of Dajjal in the two Holy cities will be prevented by the grace of Allah, through His angels standing guard at the doors.
The Messenger of Allah has referred to the Dajjal as the Masih-ul-Kazzab in some places and the Masih-ud-Dajjal in others. from Abu Huraira (ra), - Bokhari, Muslim. Abu Bakr (ra), Obaydah (ra) bin Samawet, - Abu Daud. The Messenger of Allah has used the same word 'Masih' to denote the Messenger Isa (a.s.). -Bokhari, Muslim, Tirmizee.
I believe it needs no further explanation or justification that the Dajjal should be called the 'Masih-ul-Kazzab' or the 'Masih-ud-Dajjal' since it is the greatest impostor of all times, the usurper of Allah's sovereignty and the one to call upon mankind to accept it as their 'rub' or lord. However, the thought provoking part is that this word, 'Masih' has also been used both in the Qur'an and the Messenger's Hadis to refer to the Messenger Isa (a.s.) (Jesus). At first thought it does sound strange that a word used to describe a Messenger of Allah should also denote the greatest Impostor of all. However, it is soon cleared up once we understand the meaning of this word. In the Arabic language, the word 'Masih' means to envelope, cover, embrace or engulf. In that sense, both Isa (a.s.) the Messenger and the Dajjal the deceiver are 'Masih' since both their ideas are spread all over the globe. Despite the fact that Isa (a.s.) was sent strictly for the children of Israel, his teachings did not remain limited there, as I have explained earlier in the Chapter- Importance of the Dajjal's emergence. In his absence, Paul and his other disciples transcended that barrier and their preaching of a new faith resulted in the birth of Christianity and consequently, the Dajjal. Following the industrial and cultural revolutions, the Christian powers amassed great wealth and military might that enabled their colonization of almost the whole of the earth's surface. Between their influence and the untiring efforts of the Christian missionaries, they have been successful in turning Christianity into the numerically largest of the world religions and there is no place on the earth where Christianity has not spread and thus it envelopes the earth. Although the present day Christianity is far from the actual faith preached by the Messenger Isa (a.s.), it goes by his name and hence can be correctly said to 'mus' or engulf the entire world.
This is the reason for Isa's (a.s.) title as the 'Masih'. On the other hand, the Dajjal sprung from the human distorted religion of the Messenger Isa (a.s.) and has enveloped the entire world with its might; in that respect, the Dajjal too is a 'Masih'. It has been referred to as the 'Masih-ul-kazzab' as well, since it is to engulf the world with its dazzling facade, hence the lying, deceiving 'Masih'.
