What does Allah Almighty say about Justice for all in an Islamic State?

1- Justice in the Islamic State:

Allah Almighty in the Noble Quran commands the Muslims to be just and fair to everyone:

"O ye who believe! Stand out firmly For justice, as witnesses To Allah, even as against Yourselves, or your parents, Or your kin, and whether It be (against) rich or poor: For Allah can best protect both. Follow not the lusts (Of your hearts), lest ye Swerve, and if ye Distort (justice) or decline To do justice, verily Allah is well-acquainted With all that ye do. (The Noble Quran, 4:135)"

"O ye who believe! Stand out firmly For Allah, as witnesses To fair dealing, and let not The hatred of others To you make you swerve To wrong and depart from Justice. Be just: that is Next to Piety: and fear Allah. For Allah is well-acquainted With all that ye do. (The Noble Quran, 5:8)"

"But if anyone earns A fault or a sin And throws it on to one That is innocent, He carries (on himself) (Both) a falsehood And a flagrant sin. (The Noble Quran, 4:112)"

"Allah commands justice, the doing Of good, and liberality to kith And kin, and He forbids All shameful deeds, and injustice And rebellion: He instructs you, That ye may receive admonition. (The Noble Quran, 16:90)"

"...Help ye one another In righteousness and piety, But help ye not one another In sin and rancour: Fear Allah: for Allah Is strict in punishment. (The Noble Quran, 5:2)"

"And if ye do catch them out, Catch them out no worse Than they catch you out: But if ye show patience, that is indeed the best (course) For those who are patient. (The Noble Quran, 16:126)"

There is a mistranslation: The Arabic word for "ye do catch them out" is "aaqabtum" which literally means "punish" or "to punish". The correct and more accurate translation is as follows:

"And if ye punish, then punish as ye were punished (by them). But if ye show patience, that is indeed the best (course) For those who are patient. (The Noble Quran, 16:126)"

As we clearly see in all of the Noble Verses above, Muslims must not take sides and be prejudice when it comes to justice. A Muslim is commanded by Allah Almighty to stand out for Justice even if it's against his own child. Injustice is not tolerated in Islam and Allah Almighty promised those who deliberately do injustice a great punishment in Noble Verse 4:112 above.

2- Allah Almighty will not show mercy on those who never show mercy on others:

Let us look at what Prophet Muhammad peace be upon him said:

Narrated Jarir bin 'Abdullah: "Allah's Apostle said, 'Allah will not be merciful to those who are not merciful to mankind.' (Translation of Sahih Bukhari, ONENESS, UNIQUENESS OF ALLAH (TAWHEED), Volume 9, Book 93, Number 473)"

The Muslim needs to always be polite, humble, patient, loving and well mannered when he/she deals with others, whether they were Muslims or non-Muslims. Allah Almighty certainly doesn't love those who are offensive and rude to others:

"Allah forbids you not, With regard to those who Fight you not for (your) Faith Nor drive you out Of your homes, From dealing kindly and justly With them: For Allah loveth Those who are just. (The Noble Quran, 60:8)"

Great Post. Jazakallah.
