What Islam says about justice
Justice in Islam runs from a name of God down to the timing of a wage payment. The Qur'an makes fairness a duty even when it costs you, and the hadith literature applies the same principle to a single transaction. The ten entries below move from the idea to its applications. Each carries the source the library cites, and each links to its full page.
'Adl - Justice
The command is to stand firm in justice even when the verdict goes against yourself, your parents or your relatives. Kinship is named directly, because it is the loyalty most likely to bend a judgement.
Surah An-Nisa 4:135
Al-Hakam - The Judge
Justice is one of the names by which God is known, not only a rule for people. That grounds the human duty in something other than social agreement.
Surah At-Tin 95:8
Equality Before Allah
Human difference is described as a means of knowing one another, and standing is assigned by conduct alone. Tribe and nation are mentioned in order to be demoted.
Surah Al-Hujurat 49:13
Zakat - Purification of Wealth
An obligatory annual payment on accumulated wealth, separate from voluntary giving. Calling it purification frames wealth that has not been shared as something needing to be cleaned.
Surah At-Tawbah 9:103
Protection of the Oppressed
Standing with those who cannot defend themselves is stated as a duty rather than a virtue. The verse names women and children specifically.
Surah An-Nisa 4:75
Rights of Workers
Pay the worker before his sweat dries. The instruction is about timing, which is where wage injustice usually happens in practice.
Sunan Ibn Majah, Book 16, Hadith 2443
Prohibition of Interest - Riba
Trade is permitted and interest is forbidden. The line being drawn is between profit from shared risk and profit from another person's need.
Surah Al-Baqarah 2:275
Care for Orphans
Providing for the orphan is a repeated command, and the verse cited praises giving food while still wanting it yourself. Justice here is costly rather than surplus.
Surah Al-Insan 76:8
Neither Harm Nor Reciprocate Harm
Do no harm, and do not answer harm with harm. The second half is the harder one, and it closes off revenge as a remedy.
Sunan Ibn Majah, Book 13, Hadith 2340
Enjoining Good and Forbidding Evil
Wrongdoing is treated as a collective responsibility, not only a private failing. How that duty is carried out without becoming coercion is contested, and this concept does not settle it.
Surah Ali 'Imran 3:110
The through-line is that justice is owed outward, including to people who cannot make you pay. Several of these entries are uncomfortable by design: the wage rule indicts ordinary delay, and the command to testify against your own family leaves no room for a private exception.
