Does the squeezing of the the grave mentioned in the Hadith: "The grave has a squeeze; if anyone were to escape it, Sa'd ibn Mu'adh would have escaped it," include prophets, righteous people, martyrs, and the truthful, and is there any way to prevent it?

The prophets are exempt from the compression of the grave, and this is what many scholars have stated. They supported this by arguing that the prophets are infallible from major and minor sins. Al-Suyuti, Al-Manawi, Al-Nafrawi, Al-Bujairimi, and Al-Rajhi mentioned this exception. However, the exception of others besides the prophets, such as the righteous and saints, has not been proven. Al-Bujairimi mentioned the exception of Fatimah bint Asad, but it is a weak hadith.
