Narrated Ibn ‘Abbas (raa): ‘Ukaz, Majanna and Dhul-Majaz were market-places in the Pre-lslamic period of ignorance (Jahiliyyah).
When Islam came, Muslims felt that marketing there might be a sin. So, the Divine Inspiration came:
Al Baqarah – Surah 2. The Cow
[2:198] “There is no harm for you to seek the bounty of your Lord (in the seasons of Hajj).”
Ibn ‘Abbas recited the Verse in this way.
