What saves from the punishment from the grave

The good deeds:

RasulAllah sallallahu ‘alayhi wa sallam said, “When the dead person is buried, he is able to hear the footsteps of the people when they are leaving the cemetery. Then his good deeds will surround him. So Salah would come next to his head; fasting would come on his right side and Zakah would come on the left side. The other good deeds would come next to his feet. So whenever this person would be attacked from the head, the salah would say, ‘No you cannot come from this side.’ And whenever the attack is from the right side, the siyaam [fasting] would say, ‘No, you cannot come from this side.’ The Zakah would say, you cannot come from this side. And the other good deeds would say, you cannot from the feet. And they would be making a shield, surrounding this person from every side and protecting this person.”

Seeking refuge in Allah from the punishment of the grave

The Prophet sallallahu ‘alayhi wa sallam said, “When you make tashahud, seek refuge in Allah from four things: from punishment of the hell fire, from the punishment of the grave, from the fitna of life and death, and from the fitna of ad-dajjal (the false messiah). It is a sunnah to say this [Du'aa`] during salah, after tashahud (before salaam).
