Appearance
Completion and Perfection of Religion
The Qur’anic verse stands as a profound declaration of the culmination of the divine message:
“This day have those who disbelieve despaired of your religion, so fear them not, and fear Me. This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as your religion.”
Revealed during the Prophet Muḥammad’s (s.a.w.) final pilgrimage, this verse signifies a pivotal moment in the history of Islam, marking the perfection of the faith and the completion of God’s favor upon the believers. In Tafsīr al-Mīzān, ʿAllāmah Ṭabāṭabāʾī examines this verse with meticulous detail, exploring its historical, theological, and structural implications, while addressing the significance of divine guardianship (wilāyah) as the cornerstone of Islam’s perfection and preservation.
One of the first observations made by ʿAllāmah is the verse’s unique placement within a passage primarily concerned with dietary laws. While the surrounding text outlines legal prohibitions, this declaration of perfection appears as an interjection, distinct in its weight and meaning. Such parenthetical speech highlights the verse’s elevated status, transcending the immediate legal discourse to deliver a universal and eternal proclamation. The opening phrase “This day…” signals a specific turning point, an event that altered the trajectory of the Muslim community, securing Islam’s structure for all time.
The identity of “This day” has been a subject of debate among scholars, with some suggesting moments such as the early days of Islam, the conquest of Mecca, or the Farewell Pilgrimage. However, ʿAllāmah argues convincingly that this verse refers to the significant event at Ghadir Khumm, where the Prophet Muḥammad (s.a.w.) appointed ʿAli (a.s.) as his successor. On the 18th of Dhi al-Hijjah in the 10th year of Hijra, the Prophet gathered his followers, taking ʿAli’s hand and proclaiming, “For whomever I am his master (mawlā), this ʿAli is his master.” This declaration established ʿAli’s spiritual and political guardianship over the Muslim community, ensuring the continuity of divine leadership. In linking this event to the verse, ʿAllāmah highlights that the perfection of religion lies not merely in the delivery of laws and principles but in the provision of divinely appointed leadership to safeguard and uphold the faith.
The phrase “This day those who disbelieve have despaired of (defeating) your religion” serves as a declaration of the disbelievers’ loss of hope in undermining Islam. Historically, the enemies of Islam believed that the Prophet’s death would mark the end of the faith, particularly because he left no male heir. To them, Islam appeared as a temporary disturbance, destined to fade away with its founder’s passing. However, the appointment of ʿAli (a.s.) shattered these expectations. By establishing a clear line of succession, the Prophet ensured that Islam would be protected and preserved. This realization brought despair to the disbelievers, as they understood that the faith had been fortified against decline. With this declaration, God shifts the believers’ focus: “Fear them not, but fear Me,” redirecting their vigilance away from external threats and toward their accountability before God.
The verse continues with “This day I have perfected for you your religion and completed My favor upon you.” Here, the concept of divine favor (niʿmah) is explored as central to Islam’s perfection. For ʿAllāmah, this favor is embodied in the institution of wilāyah—the divinely sanctioned guardianship that extends from the Prophet to Imām ʿAli (a.s.) and the imāms from his lineage. Wilāyah is not a mere form of political leadership but a comprehensive guardianship encompassing spiritual, moral, and legislative authority. It ensures that the Muslim community remains connected to divinely guided leadership, preserving the faith’s purity and protecting it from deviation. This guardianship is both an act of divine mercy and a practical necessity, offering Islam stability, continuity, and resilience against external and internal threats.
The perfection of religion, as declared in this verse, lies in the establishment of a self-sustaining system. Islam’s laws and principles are complete, but their preservation and proper application depend on leadership that is both divinely appointed and spiritually pure. The Prophet’s appointment of Imām ʿAli (a.s.) ensured that this leadership would remain intact, providing the community with a source of guidance that aligns perfectly with divine will. By entrusting the faith to the imāms, God guaranteed that Islam would continue as a living tradition, capable of addressing the challenges of any era while preserving its foundational integrity.
ʿAllāmah emphasizes that this perfection is not static; it reflects the dynamic resilience of Islam under divine guardianship. The phrase “completed My favor” signifies the fulfillment of God’s promise to provide the Muslim community with the tools necessary for success in both this world and the hereafter. With the institution of wilāyah, Islam transcends being a mere set of doctrines and practices; it becomes an enduring and adaptable system, anchored in divine wisdom and upheld by divinely appointed leaders.
The verse also addresses the believers’ responsibility to honor this perfection. The command “Fear Me” serves as a reminder of their accountability before God. Previously, fear of external enemies was justified by the fragile state of the early Muslim community. Now, with the faith fortified and its leadership secured, the believers are called to shift their focus inward, ensuring their own commitment to upholding and preserving the perfected religion. This advisory command emphasizes the weight of their responsibility: the continuity of Islam now rests upon their recognition and adherence to the divine trust of wilāyah.
In conclusion, the verse “This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as your religion” marks the fulfillment of God’s plan for humanity. The perfection of Islam, as explained by ʿAllāmah Ṭabāṭabāʾī, lies in its comprehensive system of beliefs, laws, and leadership. The event at Ghadir Khumm, where Imām ʿAli (a.s.) was appointed as the Prophet’s successor, represents the establishment of wilāyah as the cornerstone of this perfection. Through divine guardianship, Islam became a complete and self-sustaining system, preserved against distortion and capable of guiding humanity across generations. The verse serves as both a declaration of divine completion and a call to action, reminding believers of their role as custodians of this perfected faith. In honoring this trust, they ensure that Islam remains a beacon of guidance, justice, and mercy for all time.
The phrase “This day” signifies a pivotal turning point. Numerous traditions identify Ghadir Khumm as the context of revelation for this verse. Tafsīr works like Tafsīr al-Kashshaf (Zamakhshari) and Tafsīr al-Razi reference the significance of leadership in this verse. ↩︎

During the early Islamic period, disbelievers hoped that internal disunity or lack of leadership would weaken the Muslim community. This verse marks their realization that divine leadership ensures Islam’s endurance. ↩︎
Niʿmah (favor) in this verse refers to divine blessings that include the revelation of Islam and the appointment of leadership to safeguard it. ʿAllāmah emphasizes that this favor finds its culmination in the establishment of wilāyah. Shia exegetes often cite the Hadīth al-Thaqalayn as a complementary tradition where the Prophet states: “I leave behind me two weighty things: the Book of God and my Progeny.” This hadīth supports the idea that divine favor includes the provision of leadership.
