It is narrated from Hazrat Malik that it was written in the Zabur: I am Allah, there is no deity except Me, I am the King of all kings, the hearts of all kings are in My control. So, when a nation does good deeds, I appoint a kind king over them, and when a nation disobeys Me, I make the kings a trial for them. Do not occupy yourselves with speaking ill of the kings, nor turn towards them; turn towards Me and repent, and I will make them merciful to you.
