Worship becomes sincere, since it is directed to none but Him.

Worship becomes sincere, since it is directed to none but Him. Such a worldview liberates the soul from dependence on worldly powers and instills serenity rooted in divine trust. ʿAdl – Divine Justice The second pillar of the Usul al-Din is ʿAdl, the principle of Divine Justice. Unlike some Islamic schools that emphasize predestination, Shia theology highlights that Allah’s actions are inherently just and purposeful.

God does not commit oppression nor injustice [12] ; everything He decrees is in harmony with wisdom and fairness. Shaykh al-Muzaffar, in his The Faith of the Imamiyyah Shi’ah , writes: “ We believe that one of Almighty Allah’s positive Attributes of Perfection is that He is absolutely Just and is never unjust. He never wrongs anyone through His acts and never treats anyone unfairly through His judgments. He rewards His obedient servants and has the right to punish the disobedient.

He never takes His servants beyond their scopes and never punishes them beyond the limits of what they deserve.” It is believed that ʿAdl is not just an attribute of God but a fundamental component of faith. Belief in Divine Justice distinguishes Shia Islam, as it affirms that human beings are morally responsible for their actions. Every notion claiming that Allah has wronged His servants is an injustice to Him, Glory be to Him.

The origin of an ugly act does not go beyond ignorance, helplessness, need, and rashness, and Allah Almighty is above all of them. …Likewise, every notion that says Allah lacks wisdom in His creation, sustenance, trials, and all his actions is unjust to Him [13] . Nubuwwah – Prophethood The third pillar of the Usul al-Din is Nubuwwah , the belief in Prophethood. In Shia theology, prophets are divinely chosen guides who convey God’s message to humanity, exemplifying moral and spiritual perfection.

Their mission, as emphasized in the Qur’an, [14] ensures that human beings can understand divine law, distinguish right from wrong, and cultivate a life pleasing to Allah. It is an obligation to believe in all of the prophets (AS) and the messages revealed to them by their Lord. It is well known from narrations that there were 124,000 prophets and messengers, beginning with Adam (AS) and ending with our (PBUHH) [15] .

A central tenet of Shia belief is that (PBUHH) is the Seal of Prophets, the final messenger of God, whose message is complete and universal.
