Abu al-Hasan (PBUH) said...
Abu al-Hasan (PBUH) said: There are certain disciples of Allah who accompany the rulers for guarding Allah’s disciples. (According to another report,) Those are the ones whom Allah will save from Hell. Imam as-Sadiq (PBUH) said: The expiration of holding governmental authorities is to settle the needs of the friends.
A man asked Imam as-Sadiq (PBUH) to write a message to an-Najashi, the treasury official of al-Ahwaz and Persia, to cancel the debts that he owed his office, since an-Najashi was Shiite. The Imam did, and the man carried that message to an-Najashi and handed it over to him when they were alone. In that message, the Imam (PBUH) wrote: In the Name of Allah the Compassionate the Merciful.
Please your brother and Allah will please you. As he read the message, an-Najashi kissed and put it between his eyes and asked the man about his need. I owe your office ten thousand dirhams, said the man. An-Najashi asked his secretary to cancel the debt and record ten thousand dirhams that the man would have the next year. He then took out ten thousand dirhams and gave to the man and asked, Have I pleased you? Yes, you have, answered the man.
An-Najashi took another bag of ten thousand dirhams and gave to the man and asked, Have I pleased you? Yes, you certainly have, said the man. An-Najashi went on giving that man everything, including a riding animal, a bond maiden, and a servant, and asking whether he had pleased him until it was the turn of the rug on which he was sitting. He also asked the man to provide all his needs so that he would settle them. The man came to Imam as-Sadiq (PBUH) and told him of the whole story.
The Imam was highly delighted. Son of Gods Messenger, asked the man, Are you pleased by that which an-Najashi had done to me? The Imam answered: Yes, indeed, by Allah. His deed has also pleased Allah and His Messenger. Bad Consequences of Injustice To deem ugly and deny injustice is a natural quality of humankind. The free spirits refute injustice and exert all efforts for fighting against it. Commonness of injustice is the most dangerous epidemic on societies, since it causes social collapse.
To overlook acts of injustice encourages the oppressors to go beyond the limits in aggression and criminality. It also enjoins the oppressed people to revenge themselves upon others. Such being the case, disorder will be common. All this will certainly produce dissolution of nations as well as loss of security and luxury.
