Imran bin Husayn reported,
The Messenger of Allah ﷺ said, "A group of my nation will continue to stand firm upon the truth, prevailing over those who oppose them, until the command of Allah comes and Isa son of Maryam descends."
Azami 720
Sahihعن عمران بن حصين
أن رسول الله ﷺ قال: لا تزال طائفة من أمتي على الحق ظاهرين على من ناوأهم حتى يأتي أمر الله، وينزل عيسى ابن مريم.
and his killing of Dajjal and his killing of DajjalImam Ahmad narrated it (19851) from Bahz, who said, Hammad bin Salama narrated to us, who said, Qatada narrated to us, from Mutarrif, from Imran bin Husayn, and he related it. Its isnad is sahih. Abu Dawud (2484) and Imam Ahmad (19920) also narrated it, and Hakim graded it sahih (2/71, 4/450), all of them through another route from Hammad bin Salama with his isnad, and they said in it, instead of his words, "until the command of Allah comes and Isa bin Maryam descends," "until the last of them fights the Antichrist Dajjal." He is Isa bin Maryam, because he will descend at the end of time, confirming the law of Muhammad ﷺ and renewing it, since there is no prophet after the Messenger of Allah ﷺ, for he is the seal of the prophets, so Isa bin Maryam will be from his nation, and he is the one who will fight Dajjal and destroy him.
