The Establishment of the Hijri Calendar refers to the historic decision made during the caliphate of Umar ibn al-Khattab (RA) in 638 CE to adopt the lunar calendar with the Hijrah (migration) of the Prophet Muhammad (PBUH) from Mecca to Medina as its starting point. This decision, made in consultation with the companions, established the Islamic calendar that remains in use today for determining religious observances. This event represents the peak of Islamic administrative Itqan (perfection) and the Nur (light) of a civilization that organized its time around the most significant event in its history. It serves as a definitive Hujjah (proof) of the wisdom of the early Caliphate and the importance of a unified calendar for the Ummah, providing the believers with the Sakina (tranquility) and the structure needed to mark sacred time for the pleasure of their Lord.
Theologically, the establishment of the Hijri calendar is a manifestation of the principle of Divine Guidance and the Hikmah (wisdom) of Divine law in the organization of time. It reflects the Nur of a faith that views the Hijrah as the turning point in Islamic history, marking the transition from persecution to establishment. The adoption of the lunar calendar for religious purposes serves as a Burhan (proof) of the intellectual and moral vitality of the Islamic tradition, which integrates historical events with the rhythm of worship. This history reflects the Mizan (balance) between the natural cycles of the moon and the historical significance of the Hijrah. Historically, the Hijri calendar has provided the Ummah with the moral resilience and the social stability needed to maintain a unified sense of time across the global community. It underscores the absolute duty of every believer to honor the Hijrah and to be a witness to humanity through the power of integrity and radiant achievement.
For the modern Ummah, the legacy of the Hijri calendar is a source of immense pride and a roadmap for contemporary spiritual and communal reform. It teaches the believers the value of unity, the beauty of unshakeable faith, and the importance of maintaining an ethical and honest relationship with the rhythm of sacred time. In a modern world often characterized by disconnection from religious time, the tradition of "The Hijri Calendar" provides a roadmap for internal peace and communal solidarity. It encourages a culture of Ihsan (excellence) and communal responsibility. By honoring the calendar established by Umar (RA), the Muslim community strengthens its identity and its commitment to the values of the Quran. It promotes a life of purpose and shared prosperity, ensuring that the light of truth continues to guide the human condition.
