Al-`Adl
Allah is Al-Adl, The one who rectifies and sets matters straight in a just and equitable manner. He always delivers absolute justice through His wisdom without failure. He gives to each what he deserves and puts everything in its proper order.
From the root ‘a-d-l which has the following classical Arabic connotations: to act justly, fairly to be equitable, impartial to adjust properly, to make even to straighten, to rectify, to establish justice to balance, counterbalance, to make equal, uniform to turn one away from something, rightly direct to make comfortable with what is right.
The term ‘Adl is not used directly in The Quran. Yet there are verses regarding his justice.
Indeed, Allah does not do injustice, [even] as much as an atom’s weight;
while if there
is a good deed, He multiplies it and gives from Himself a great reward. (Quran 4:40)
And the word of your Lord has been fulfilled in truth and in justice. None can alter His words, and He is the Hearing, the Knowing. (Quran 6:115)
Abdullah ibn Amr reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, those who were just will be in the presence of Allah upon pulpits of light, near the right hand of the Merciful, the Exalted, and both of His sides are honorable. They are those who practiced justice in their judgments and with their families and in all that they did.”
