Assalaam Alaikum Wa Rahmatullahi Wa Barakatuh,
Jazakallahu Khair for remindering! Scholar Bediuzzaman Said Nursi's interpretation for the hadiths mentioned in your thread:
At the end of time two currents of irreligion will gain strength.
One of them: Under the veil of duplicity, a fearsome individual named the Sufyan will deny the messengership of Muhammad (PBUH), and coming to lead the dissemblers, will try to destroy the Islamic Shari‘a. To oppose him, a luminous individual called Muhammad Mahdi of the Family of the Prophet will come to lead the people of sainthood and perfection, who are bound to the luminous chain of the Family of the Prophet, and he will kill the current of dissemblers, which will be the collective personality of the Sufyan, and scatter it.
The Second Current: A tyrannical current born of Naturalist and Materialist philosophy will gradually become strong and spread at the end of time by means of materialist philosophy, reaching such a degree that it denies God. A savage who does not recognize the king or accept that the officers and soldiers in the army are his soldiers ascribes a sort of kingship and rulership to everyone and to all the soldiers. In just the same way, the members of that current, who deny God, each ascribes dominicality to his soul like a little Nimrod. And the greatest of them, the Dajjal, who will come to lead them, will manifest awesome wonders, a sort of spiritualism and hypnosis; he will go even further, and imagining his tyrannical, superficial rule to be a sort of dominicality, he will proclaim his godhead. It is clear just what foolish buffoonery it is for impotent man, who may be defeated by a fly and cannot create even a fly’s wing, to claim godhead.
At that point when the current appears to be very strong, the religion of true Christianity, which comprises the collective personality of Jesus (Upon whom be peace), will emerge. That is, it will descend from the skies of Divine Mercy. Present Christianity will be purified in the face of that reality; it will cast off superstition and distortion, and unite with the truths of Islam. Christianity will in effect be transformed into a sort of Islam. Following the Qur’an, the collective personality of Christianity will be in the rank of follower, and Islam, in that of leader. True religion will become a mighty force as a result of its joining it. Although defeated before the atheistic current while separate, Christianity and Islam will have the capability to defeat and rout it as a result of their union. Then the person of Jesus (Upon whom be peace), who is present with his human body in the world of the heavens, will come to lead the current of true religion, as, relying on the promise of One Powerful Over All Things, the Bringer of Sure News has said. Since he has told of it, it is true, and since the One Powerful Over All Things has promised it, He will certainly bring it about.
It says in narrations : “The Dajjal’s first day will be a year, his second day a month, his third day a week, and his fourth day a day.” None knows the Unseen save God, this may be interpreted in two ways:
The First: It is an allusion and sign that the Great Dajjal will appear near the North Pole or towards the north. For close to the North Pole the whole year is one day and one night. If he comes a day’s journey in this direction by train in the summer, for a month the sun never sets. If he comes a day further in this direction, the sun is visible for a whole week. When I was a prisoner-of-war in Russia I was close to this region. That means it foretells miraculously that the Great Dajjal will attack from the North in this direction.
The Second Interpretation: The three days refer to both the Great Dajjal and the Islamic Dajjal having three periods of despotism. With elevated eloquence it informs the Umma that “in his first day; in his first period of government, he will perform works so great they could not be performed in three hundred years. On his second day, that is, in his second period, he will carry out such works as could not be carried out in thirty years. In his third day and period, the transformations he will bring about could not be brought about in ten years. While in his fourth day and period he will be reduced to the ordinary and do nothing, only try to maintain his position.”
