Sahih Bukhari | Volume 3 | Hadith Number 266
Narrated by Ibn 'Abbas
'Ukaz, Majanna and Dhul-Majaz were market-places in the Pre-Islamic period of ignorance. When Islam came, Muslims felt that marketing there might be a sin. So, the Divine Inspiration came: "There is no harm for you to seek the bounty of your Lord (in the seasons of Hajj)." (2:198) Ibn 'Abbas recited the Verse in this way.
