A believer is afflicted due to 2 reasons, due to a sin that can only forgiven due to it or due to a status that can only be reached through it.\n\nThe grave will become a garden of Paradise for the one whom the remembrance of death frightens (Jam'ul Jawwami).\n\nWhen a disciple of Prophet Isa (as) was lowered into the grave, he said\n\nWere you not in a more constricted place than this when you were in your mothers womb, but if Allah SWT wishes to expand something He expands it (Ibn Abee Dunyaa).
