Narrated Abdullah ibn Abbas: The people used to trade, in the beginning, at Mina, Arafat, the market place of Dhul-Majaz, and during the season of hajj. But (later on) they became afraid of trading while they were putting on ihram. So Allah, glory be to Him, sent down this verse: "It is no sin for you that you seek the bounty of your Lord during the seasons of hajj. " Ubayd ibn Umayr told me that he (Ibn Abbas) used to recite this verse in his codex.
