There is no sin on you if you seek the Bounty of your Lord (during pilgrimage by trading, etc.). Then when you leave 'Arafat, remember Allah (by glorifying His Praises, i.e. prayers and invocations, etc.) at the Mash'ar-il-Haram. And remember Him (by invoking Allah for all good, etc.) as He has guided you, and verily, you were, before, of those who were astray.
