Imam Ali (AS) said, Do you not see the people of this world passing the evenings and mornings in different states? The dead being mourned and the living being condoled, the victim being afflicted and the visitor visiting him [to ask about his condition], and another who is sacrificing himself; and the one who is seeking this world while death seeks him; and the one who is heedless but not neglected; and those who remain behind continue to follow the footsteps of the those who preceded [them].
