Is the grave in which the deceased is questioned about the trial of the grave and in which he is punished or granted bliss, the same grave in which he is buried?

The apparent meaning of "grave" is the place where the deceased is buried. The evidence for this is the hadith of Ibn Abbas in the Two Sahihs: that the Prophet, peace and blessings be upon him, passed by two graves and said: "Indeed, they are being tormented, and they are not being tormented for a major sin."
