سورة Al-Baqarah ( The Cow ) - الآية 197

For Hajj are the months well known. If any one undertakes that duty therein, Let there be no obscenity, nor wickedness, nor wrangling in the Hajj. And whatever good ye do, (be sure) Allah knoweth it. And take a provision (With you) for the journey, but the best of provisions is right conduct. So fear Me, o ye that are wise.
