The ruling on one who denies the descent of 'Isa, the emergence of the Dajjal, and the appearance of the Mahdi

The second question also states: We have a man who denies the Christ the Dajjal, the Mahdi, and the descent of 'Isa (peace be upon him), as well as Gog and Magog, and he does not believe in any of these matters. He claims that the reports regarding these matters are not authentic, despite the fact that he knows nothing about the science of hadith or any other science. He has been discussed by scholars regarding these matters before; however, he claims that all the hadiths regarding these matters are fabricated against the Prophet (peace and blessings be upon him) and are foreign to Islam. He prays, fasts, and performs the obligatory acts, so what is his ruling? May Allah guide you.
Answer: A man like this is a disbeliever, we seek refuge in Allah; because he denied something established from the Messenger of Allah (peace and blessings be upon him). If the people of knowledge explained it to him and clarified it, and yet he persisted in lying about it and denying it, he is a disbeliever; because whoever lies about the Messenger (peace and blessings be upon him) is a disbeliever, and whoever lies about Allah is a disbeliever. These reports are authentic and mass-transmitted from the Messenger of Allah regarding the descent of the Christ, son of Maryam, from the sky in the end times, the emergence of Gog and Magog, the emergence of the Dajjal in the end times, and the coming of the Mahdi. All four of these are established. The Mahdi in the end times will fill the earth with justice after it has been filled with injustice, the descent of the Christ, son of Maryam, and the emergence of the Dajjal in the end times, and the emergence of Gog and Magog. All of this is established by authentic, mass-transmitted hadiths from the Messenger of Allah (peace and blessings be upon him). Denying them is disbelief and misguidance. We ask Allah for safety and well-being. Yes.
The first question, which concerns the Dajjal, the Dajjal, and the Christ, son of Maryam, and Gog and Magog: there is no doubt, without question, that reports regarding these three are mass-transmitted from the Messenger (peace and blessings be upon him). As for the Mahdi, reports regarding him are also mass-transmitted, and more than one scholar has narrated that they are mass-transmitted from the Prophet (peace and blessings be upon him). However, some people have an issue with it and hesitate. It may be said: one should hesitate regarding the disbelief of one who denies only the Mahdi alone. As for one who denies the Dajjal, or the Christ, son of Maryam, or Gog and Magog, there is no doubt in his disbelief and no hesitation. The hesitation is only regarding one who denies only the Mahdi. It may be said: one should hesitate regarding his disbelief and his apostasy from Islam; because it has come that some before him had difficulty with that. The most apparent and closest view in this is that he is a disbeliever; but some scholars hesitate regarding that. As for what concerns Gog and Magog, the Dajjal, and the Christ, son of Maryam... whoever denies these three or one of them has become a disbeliever. We ask Allah for safety. Yes.
