What is meant by the "squeeze of the grave," and does it encompass both the soul and the body, and what is the meaning of the displacement of the ribs?

It has been established that the compression of the grave for the deceased is a Sunnah, and it is the first thing the deceased encounters in the Barzakh. No one escapes it, and it occurs to the body when the soul is connected to it. For the disbeliever, the hypocrite, and the disobedient, it is a form of torment and punishment. As for the believer, it is an expiation for the sins and pains that Allah has decreed upon him. The severity and gentleness of the compression vary according to the state of the deceased.
