QS. Al-Baqarah [2:197]

alhajju asyhurun ma'luumaatun faman faradha fiihinna alhajja falaa rafatsa walaa fusuuqa walaa jidaala fii alhajji wamaa taf'aluu min khayrin ya'lamhu allaahu watazawwaduu fa‑inna khayra alzzaadi alttaqwaa wattaquuni yaa‑ulii al‑albaabi

Hajj is [during] well-known months, so whoever has made Hajj obligatory upon himself therein [by entering the state of ihram], there is [to be for him] no sexual relations and no disobedience and no disputing during Hajj. And whatever good you do - Allah knows it. And take provisions, but indeed, the best provision is fear of Allah. And fear Me, O you of understanding. [197]
