Chapter on the Greater and Lesser Pilgrimages

"I asked Abu Abdullah (as) about the Day of the Greater Pilgrimage (Yawm al-Hajj al-Akbar). He said, 'It is the Day of Sacrifice (Yawm al-Nahr), and the Lesser Pilgrimage (al-Asghar) is the Umrah.'"

"It was called the Greater Pilgrimage (Hajj al-Akbar) because it was the year in which both Muslims and polytheists performed Hajj, and after that year, the polytheists no longer performed Hajj."
