The phrasing "Islam is a journey to a city" misunderstands both the religion and the practice. Hajj (pilgrimage to Mecca) is one of Islam's Five Pillars—obligatory once for able Muslims. But Islam itself is a comprehensive way of life: theology (tawhid, oneness of God), scripture (Qur'an), prophetic tradition (Sunnah), law (Sharia), ethics, community (ummah), and eschatology.
Annual pilgrimage (8th–12th Dhul Hijjah) to Mecca, Saudi Arabia. Rituals: ihram (consecrated state), tawaf (circling Kaaba), sa'i (walking Safa-Marwa), wuquf (standing at Arafat), ramy (stoning pillars), udhiyah (sacrifice), tawaf al-ifadah. ~2–3 million pilgrims yearly.
Hajj is worship—ibadah—not travel. The destination matters because the Kaaba (built by Ibrahim/Abraham) is the qibla (prayer direction) for all Muslims worldwide. The city is the vessel; the devotion is the substance.
Reducing Islam to "a journey to a city" erases 1,400 years of theology, civilization, and 1.9 billion people's daily practice.
