(34) CHAPTER. “There is no sin on you if you seek the Bounty of your Lord (during pilgrimage by trading)...” (V.2:198)
Narrated Ibn `Abbas: `Ukaz, Mijanna and Dhul-Majaz were markets during the Pre-islamic Period. They (i.e. Muslims) considered it a sin to trade there during the Hajj time (i.e. season), so this Verse was revealed:-- There is no harm for you if you seek of the Bounty of your Lord during the Hajj season.
