There are different interpretations of the Hadith about dajjal. Different scholars have a different perspective. But there are some perceptions that can easily be denied by considering some facts from the Hadith in Sahih Muslim and Bukhari.
I would like to quote a Hadith from Sahih Muslim,
Sahih Muslim: (Book #001, Hadith #0324) (Book #001, Hadith #0327)
It is narrated on the authority of ‘Abdullah b. Umar that one day the Messenger of Allah (may peace be upon him) mentioned in the presence of people about al-Masih al-Dajjal. He said: Verily Allah (hallowed be He and High) is not blind of one eye. Behold, but the Masih al-Dajjal is blind of right eye as if his eye is like a swollen grape, and the Messenger of Allah (may peace be upon him) said: I was shown in a dream in the night that near the Ka’bah there was a man fair-complexioned, fine amongst the white-complexioned men that you ever saw, his locks of hair were falling on his shoulders. He was a man whose hair were neither too curly nor too straight, and water trickled down from his head. He was placing his bands on the shoulders of two persons and amidst them was making a circuit around the Ka’bah. I said: Who is he? They replied: Al-Masih son of Mary. And I saw behind him a man with intensely curly hair, blind of right eye. Amongst the persons I have ever seen ibn qatan has the greatest resemblance with him. He was making a circuit around the Ka’bah by placing both his hands on the shoulders of two persons. I said: Who is he? They said; It is al-Masih al-Dajjal. (Book #001, Hadith #0324)
This Hadith has been narrated in slightly different detail in all the other Sahih hadith I have referred above. But all of them have Abdul Uzza Ibn Qatan as a common reference.
Now, Who is Ibn Qatan? Abdul Uzza Ibn Qatan was a man from the al-Mustaliq tribe of Khuza’a, who died in the pre-Islamic times, and the Prophet (pbuh) referred to him as to have a greater resemblance with Dajjal. With this said, calling dajjal a system and interpreting blindness in one eye as spiritual blindess etc, are meaningless.
I would like to mention a few of those ideas which are commonly spread among people, about the Dajjal.
• Most people believe that Blind in One Eye means ‘Internal Blindness’
• Some people even say that Dajjal is in fact the Western Culture, i-e- Materialism
• Some people call the Television a Dajjal, seeing how it appears like a One-Eye, etc.
Whatever the issue may be, the above hadith clearly denies all of them. Dajjal will be a Being in Human Form, and Not a System.
