Theology – Al-Shia The al-Shia Scientific, Cultural, and Doctrinal Website Thu, 16 Oct 2025 08:25:30 +0000 en-US Theology – Al-Shia 32 32 Usul al-Din: The Five Pillars of Shia Belief This article discusses the five foundational principles of Shia belief, known as Usul al-Din: Tawḥīd (Oneness of God), ʿAdl (Divine Justice), Nubuwwah (Prophethood), Imāmah (Divinely appointed leadership), and Maʿād (the Hereafter). It begins by outlining the background of Shia theology, which combines reason and revelation to form a balanced understanding of faith. The main goal is to explain how these principles (Usul al-Din) shape a believer’s relationship with God and give structure to Shia religious thought. The findings show that Usul al-Din is not just a set of abstract doctrines but a complete guide for spiritual growth, justice, and ethical living. In conclusion, the article highlights that understanding these five roots ( Usul al-Din ) allows believers to live their Shia belief with deeper conviction, awareness, and sincerity. Background of Shia Theology In the first instance, it is pertinent to mention that the term “Usul al-Din” is not used in the Qur’an and hadiths, but was coined by Muslim scholars in order to indicate the main goals of the religion [1]. However, in some hadiths from the Prophet (PBUHH) and the Imams (a.s), some religious elements were introduced as tenets of the religion. “Usul al-Din” is a theological term that refers to the essential and foundational beliefs of Islam—those that one must affirm to be regarded as a true Muslim [2]. In Shia belief, the concept of Usul al-Din refers to the fundamental theological framework every Shia Muslim must understand and affirm through conviction rather than imitation. Unlike the Furūʿ al-Dīn (branches of religion) that focus on practical acts such as prayer and fasting, the Usul al-Din deal with the intellectual and spiritual foundations of faith [3]. As emphasized by the majority of Shia scholars, these foundational principles (Usul al-Din) are not accepted through blind imitation (taqlīd), but through understanding and conviction [4]. In his book, al-Bab al-Hadi ‘Ashar, ‘Allama al-Hilli claimed that scholars had consensus over this requirement [5]. According to al-Shahid al-Thani in Haqa’iq al-Iman, almost all Muslim scholars believe that it is not permissible to follow other people in the principles of the religion [ Usul al-Din ] [6], because the belief in such principles should be with certainty, but following other people does not provide one with certainty [7]. Al-Shaykh al-Ansari, in his al-Rasa’il, emphasizes that the mere presumption of the foundational principles of the religion [ Usul al-Din ] is not enough for one to be regarded as a true believer [8]. Based on numerous hadiths that highlight the necessity of understanding, he argues that a believer is obligated to seek knowledge of these principles and strive to attain certainty regarding them, to the extent that such understanding is possible [9]. Therefore, understanding the Usul al-Din is essential for every Muslim who wishes to strengthen his or her Shia belief. An Overview of Usul al-Din Meanwhile, these five foundational principles ( Usul al-Din ) are explained as follows: Tawḥīd – The Oneness of God At the heart of Shia belief lies Tawḥīd—the absolute Oneness and Unity of Allah. It is not only the first of the Usul al-Din but also the essence that gives meaning to every other principle of faith. Tawḥīd means affirming that God is One in His essence (dhāt), attributes (ṣifāt), and actions (afʿāl). His essence is indivisible; His attributes are not separate from His essence [10]; and all actions in existence ultimately originate from Him alone. He has no partner, no likeness, and no rival. The Qur’an declares this truth most concisely and profoundly: Say, ‘He is Allah, the One. Allah is the All-embracing. He neither begat, nor was begotten, nor has He any equal.’ (Qur’an 112:1–4) In this regard, Shaykh al-Muzaffar in his The Faith of the Imamiyyah Shi’ah, writes: “Hence, the existence of these Attributes is the same as the existence of His essence. For instance, Almighty Allah’s Omnipotence with respect to His existence is the same as His Ever-livingness, and His Ever-livingness is as same as His Existence. [11] “ This comprehensive understanding distinguishes Shia belief in divine unity from a purely abstract notion of monotheism. It calls believers to see Allah as the only true source of power, sustenance, and mercy. In practical terms, Tawḥīd shapes the believer’s inner world. When one truly affirms that only Allah controls all affairs, fear of creation diminishes and reliance on God grows. 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. Prophets are endowed with ʿiṣma —divine protection from sin and error—so that their teachings can be trusted fully. In this sense, prophets cannot do anything outside the will of Allah, and any miracles or abilities they manifested were the product of Allah’s power and will [16]. In essence, Nubuwwah connects the human soul with divine wisdom, bridging the gap between Cre
