Reference: Fataawa al-Lajnah ad-Daa.imah lil-Buhooth al-‘Ilmiyyah wal-Iftaa. – Volume 3, Page 147, Question No.3 of Fatwa No.7114
Question: It is mentioned in [a number of] prophetic ahaadeeth about the Dajjaal. What does Dajjaal mean, and is he currently present or not? And where is he [currently], and what does blind in one eye mean – about which the Prophet ﷺ mentioned, is it real or surreal?
[Please] reveal for us the reality of that which you have of the knowledge [concerning this issue], and may Allaah grant you Jannah al-Firdaws as your reward.
Response: Dajjaal is conjugated from [the verb] dajala, which means to lie and be foolish. This is because he (the Dajjaal) claims Lordship [for himself] and this is from the greatest of lies.
He is currently present, and as regards his blindness in one eye, then it is real, since the basis for any statement is reality.
And the appearance of the Dajjaal is that which has been confirmed from the Prophet ﷺ in authentic and mutawaatir (that which is narrated by such a large number of people that it is impossible that they have invented a lie) ahaadeeth.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet ﷺ and his family and his companions.
