سورة Al-Baqarah ( The Cow ) - الآية 197

The hajj [season] is in months well-known; so whoever decides on hajj [pilgrimage] therein, [should know that] there is to be no sexual contact, vicious talk, or disputing during the hajj. And whatever good you do, Allah knows it. And take provision, for indeed the best provision is Godwariness. So be wary of Me, O you who possess intellects!
