The Day of Judgment and Egress from Graves
Scholars have said that if one dreams that the Day of Judgment has occurred and they are standing before Allah, the dream is more firm and stronger in indicating the swift and hopeful manifestation of justice. Similarly, if one dreams that graves have split open and the dead are emerging from them, their vision indicates the spread of justice.
