لا إلَهَ الا اللّه there is no God, but Allah La illaha il Allah.

Eid al-Adha falls on the 10th day of Dhu al-Hijjah, the 12th month of the Islamic Lunar Calendar.

It is also celebrated during the annual Holy Pilgrimage of Hajj, in which thousands of Muslims travel to the holy city of Mecca in Saudi Arabia to worship in the Ka'bah, the most sacred site in Islam.
