According to search-discovered classical Islamic scholarship, Hajj (حج) is the sacred pilgrimage to the Kaaba in Makkah, and it is the fifth pillar of Islam. It is a mandatory religious duty for all adult Muslims who are physically and financially capable of undertaking the journey at least once in their lifetime. The rituals of Hajj, performed between the 8th and 13th of Dhul Hijjah, commemorate the devotion of Prophet Ibrahim and his family. Classical commentators like Ibn Kathir explain that the Quranic verses on Hajj establish its rites as a means of seeking Allah's forgiveness, purifying the soul, and demonstrating the unity of the global Muslim community (Ummah). The pilgrimage is a profound spiritual journey intended to strip away worldly distinctions and foster a deep sense of humility, equality, and submission to God.
