Chapter 2, Verse 198

The months of the Hajj are well known; so whoever determines to perform the Pilgrimage in these months, should remember that there is to be no foul talk, nor any transgression, nor any quarrelling during the Pilgrimage. And whatever good you do, Allah knows it. And furnish yourselves with necessary provisions, and surely, the best provision is righteousness. And fear Me alone, O men of understanding.
