Al-Baqarah 2:197

Alhajju ashhurun maAAloomatunfaman farada feehinna alhajja fala rafathawala fusooqa wala jidala fee alhajjiwama tafAAaloo min khayrin yaAAlamhu Allahuwatazawwadoo fa-inna khayra azzadi attaqwawattaqooni ya olee al-albab

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

The Hajj is (to be performed in) the months that are well-known. So whoever undertakes Hajj in them, there should be no obscenity, no sin, no quarrel in the Hajj. Whatever good you do, Allah will know it. Take provisions along, for the merit of (having) provision is to abstain (from begging), and fear Me, O men of understanding!
