"Whomsoever's master I am, Ali is also his master", a famous statement made by Prophet Muhammad on his way back from his last hajj pilgrimage on the 18th of Dhu al-Hijjah in the Islamic Calendar. The day Imam Ali, the first Imam of Shia, was chosen as Prophet Muhammad's rightful successor, is celebrated by Shia Muslims all around the world and is considered as one of their greatest Eids.
