The Book on Government (Kitab Al-Imara)
Muslim :: Book 20 : Hadith 4493
It has been narrated on the authority of 'Abdullah b. 'Umar that the Messenger of Allah (may peace be upon him) said: Behold! the Dispensers of justice will be seated on the pulpits of light beside God, on the right side of the Merciful, Exalted and GlorioUS. Either side of the Being is the right side both being equally mrneritorious. (The Dispensers of justice are) those who do justice in their rules, in matters relating to their families and in all that they undertake to do.
