What is the opinion of one who keeps the body of a deceased person, claiming that a time will come when a method is discovered to revive this dead person?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the opinion of one who keeps the body of a deceased person and puts preservatives in it to prevent it from decomposing and rotting, and claims that a time will come when something new is discovered that will infuse and revive this dead person with another life?

Answer:
What Allah willed, this is a myth. An ignorant person, what does he know? He wants to bring people who revive the dead, but except Allah the Mighty and Majestic. The dead do not come back to life except on the Day of Resurrection from the graves. They do not return to life, they do not return to this world, never. Rather, they are resurrected from the grave to the gathering and to the Hereafter; they do not return to this world. Have they not seen how We destroyed before them of the generations? They do not return to them, and indeed all of them will be gathered before Us. Yes.
So there is no dead person who returned to this world. Except if it is from the category of a temporary miracle, like what happened to the dead man of the Children of Israel who was struck with part of the cow. And like what happens to 'Isa (peace be upon him), that he revives the dead and he speaks, then he returns to death. This is from the category of miracles. Yes.
