How does one feel torment or bliss in the grave, and does one perceive time like the living?

The torment and bliss of the grave are real, and the Quran alluded to them while the authentic Sunnah explicitly stated them. It is obligatory to believe in their reality and to have faith in them. Reports have been successively transmitted from the Messenger of Allah, peace and blessings be upon him, regarding their reality and the questioning by the two angels. One should not delve into their exact nature.
