Quran's Tafhim ( explanation)
*4) Hajj-i-akbar refers to the 10th of Zil-Hajjah and is also known as Yaum-un-Nahr. This has been explained by the Holy Prophet in an authentic Tradition. On the 10th of Zil-Hajjah, during the last Haj of the Holy Prophet, he asked the people, "What is this day?" The people answered, "It is the day of Sacrifice. "
The Holy Prophet said, "This is the day of Hajj-i-akbar" Here the word Hajj-i-akbar (Great Pilgrimage) has been used in contrast to Hajj-i-asghar which the Arabs used for 'Umrah' . Thus, the Haj which is performed in the prescribed dates of Zil-Haj is called Hajj-i-akbar.
