Bismillah wa-salaatu wa-salaamu 'ala Rasulullah
As-salaamu 'alaikum wa rahmatullah, brothers and sisters in Islam. What proceeds is a lecture given by brother Jalal ibn Sa'eed, a condensed overview of the sahih ahadith concerning ad-Dajjal, his charateristics, the signs of his arrival and the abundant, severe fitnan (trials) surrounding him.
There has not been a single Messenger except that he has warned of ad-Dajjal; as for the final Messenger Muhammad salallahu 'alayhi wa salaam, Khatim an-Nabiy'in, the Seal of the Prophets, it was left to him to recieve and relate wahy (revelation) identifying the specifics of ad-Dajjal being that he was the last Prophet and so the advent of the dajjal is closer and preparation of those during and after his time is far dire. Many believers, even the most knowledgeable among us will succumb to his deception and affirm their faith in him. May we arm ourselves with the taqwa and sabr that we may resist his ways if it shall fall upon us. Ameen.
It is the very reason our beloved Rasul salallahu 'alayhi wa salaam advised that when we complete tashahhud in our salah that we should seek refuge from four things before offering tasleem:
Allahumma inni a'udu biki min adhabi jahanam
wa min adhabil qabr
wa min sharri fitnatil mahya wa'l mammat
wa min sharri fitnatil masih ad-dajjal
(O Allah! Indeed I seek refuge with You from the punishment of Hellfire
and from the punishment of the grave
and from the trials of living and of dieing
and from the trials of the false Messiah, the Antichrist)
