ʿAdl

ʿAdl, commonly translated as justice, fairness, equity, and balance, is one of the most important ethical principles in Islam and a central value of the Qurʾānic worldview. Derived from the Arabic root ʿ-d-l, which conveys the meanings of rectitude, balance, and impartiality, ʿadl denotes the obligation to give every person his or her due rights and to act with fairness in all circumstances. The Qurʾān presents justice as a divine attribute and a fundamental objective of revelation, making it an essential component of individual morality and social order.

The Qurʾān repeatedly commands believers to uphold justice without bias or favouritism. It instructs them to stand firmly for justice, even when doing so may conflict with personal interests, family ties, or communal loyalties (Qurʾān 4:135). Similarly, believers are warned not to allow hostility toward others to lead them to injustice, for justice is described as closest to taqwā (Qurʾān 5:8). In the Qurʾānic perspective, ʿadl is not merely a legal principle but a comprehensive moral virtue governing relationships between individuals, communities, and nations.

The concept of ʿadl is closely linked to the Qurʾānic understanding of human accountability before God. Since all human beings are created by God and are equal in their essential dignity, they are entitled to fair treatment and protection from oppression. The Qurʾān condemns ẓulm (injustice, oppression, wrongdoing) in all its forms and repeatedly emphasizes that God does not wrong anyone, even to the slightest degree (Qurʾān 4:40). Consequently, the establishment of justice is portrayed as a religious duty and a manifestation of obedience to God.

In the sīrah of the Prophet Muḥammad ﷺ, ʿadl occupies a central place. The Prophet was renowned for his integrity and fairness both before and after the advent of prophethood. His arbitration during the rebuilding of the Kaʿbah and his reputation as al-Amīn exemplified his commitment to justice. Following the establishment of the Muslim community in Madinah, he applied principles of justice in legal judgments, governance, diplomacy, and social relations. His decisions were characterized by impartiality, and he consistently rejected favouritism based on lineage, wealth, or social status. The Constitution of Madinah further reflected the Qurʾānic commitment to justice by guaranteeing rights and responsibilities among the various communities residing in the city.

The Sunnah al-Nabawiyyah reinforces the centrality of ʿadl. Numerous ḥadīths praise just rulers and condemn oppression. The Prophet ﷺ taught that the just will be among those granted special honour on the Day of Resurrection and warned that injustice would become darkness on that Day. His teachings established justice as a foundational principle for family life, commercial transactions, judicial procedures, and political authority.

Classical Muslim scholars regarded ʿadl as one of the highest virtues. Al-Rāghib al-Iṣfahānī described justice as the harmonious ordering of human affairs according to divine guidance, while al-Ghazālī viewed it as a cardinal virtue that regulates human desires and actions. Muslim jurists and theologians likewise considered justice indispensable for the preservation of religion, life, intellect, property, and human dignity.

Within Islamic civilization, ʿadl became a guiding principle of governance, law, and social ethics. The Qurʾān and the sunnah al-nabawiyyah present justice as a universal value transcending ethnic, tribal, and social distinctions. In the context of the sīrah, ʿadl emerges as a defining characteristic of the Prophet Muḥammad ﷺ and one of the principal objectives of his mission. Through his teachings and example, justice became a cornerstone of the moral and social order established by Islam.
