What does Islam say about Justice?

In the Name of Allah, the Most Gracious, the Most Merciful

 Islam stresses the use of justice, even if it be against one's own interest. . Here is what the Holy Qur'an says about justice:
"O believers! Stand firm for justice and bear true witness for the sake of Allah, even though it be against yourselves, your parents or your relatives. It does not matter whether the party is rich or poor - Allah is the well wisher of both. So let not your selfish desires swerve you from justice or decline to give it, then you should remember that Allah is fully aware of your actions. ." Al-Qur'an 4:135

O believers! Be steadfast for the sake of Allah and bear true witness and let not the enmity of a people incite you to do injustice; do justice; that is nearer to piety. Fear Allah, surely, Allah is fully aware of all your actions. Al-Qur'an 5:8

“...Cooperate with another in righteousness and piety, and do not cooperate in sin and transgression. Have fear of Allah. Allah is stern in punishment." Al-Qur'an 5:2

Islam stands for peace and peace cannot be achieved without establishing justice. Therefore, Islam requires all Muslims to strive for establishing justice in the land.

Islam commands Muslims to stand up against injustice, oppression, poverty, ignorance, racism, bigotry and intolerance everywhere in the world. Without justice, rights are denied, victims are created, anger gives way anarchy and extremism in its different forms gains more ground. We have had enough wars, crimes, terror and anger in human history. Now, it is time to identify the root causes and find solutions without partiality and favoritism.
