Shaikh Kulaini narrates from Imam Ja’far-as-Sadiq (a.s.) who said that once Hazrat Ali (a.s.) was suffering from the ailment of the eye. The Holy Prophet (s.a.w.s.) came to inquire about his health. He saw that Ali (a.s.) was in intense pain and was restless because of it. The Prophet asked him,
“Is this anxiety the outcome of the ailment”?
Hazrat Ali (a.s.) replied that,
“I had never witnessed such a pain before.”
The Holy Prophet (s.a.w.s.) (to console him) said,
“O Ali! When the Angel of death comes to take the spirit of the disbeliever, he brings along with him a club of fire, by which he removes his spirit and the flames of hell scream at the dying man.”
The Commander of the Faithful sat upright and said,
“O Prophet! Please explain to me the tradition (hadees), for I do not feel the pain anymore. Will the spirit of anyone from among your ummat be removed in the same manner”?
The Holy Prophet (s.a.w.s.) replied,
“Yes, three types of persons from among my ummat too will be subjected to this punishment
(1) An oppressive (Zalim) ruler,
(2) Those who unjustly usurp the rights of orphans, and
(3) The bearer of false witness.”
