Justice

{4:135} O you who believe! be maintainers of justice, bearers of witness of Allah's sake, though it may be against your own selves or (your) parents or near relatives; if he be rich or poor, Allah is nearer to them both in compassion; therefore do not follow (your) low desires, lest you deviate; and if you swerve or turn aside, then surely Allah is aware of what you do.

{5:8} O you who believe! Be upright for Allah, bearers of witness with justice, and let not hatred of a people incite you not to act equitably; act equitably, that is nearer to piety, and be careful of (your duty to) Allah; surely Allah is Aware of what you do.

{49:9} And if two parties of the believers quarrel, make peace between them; but if one of them acts wrongfully towards the other, fight that which acts wrongfully until it returns to Allah's command; then if it returns, make peace between them with justice and act equitably; surely Allah loves those who act equitably.
