Surah Al-Baqarah, Verse 197

ٱلۡحَجُّ أَشۡهُرٞ مَّعۡلُومَٰتٞۚ فَمَن فَرَضَ فِيهِنَّ ٱلۡحَجَّ فَلَا رَفَثَ وَلَا فُسُوقَ وَلَا جِدَالَ فِي ٱلۡحَجِّۗ وَمَا تَفۡعَلُواْ مِنۡ خَيۡرٖ يَعۡلَمۡهُ ٱللَّهُۗ وَتَزَوَّدُواْ فَإِنَّ خَيۡرَ ٱلزَّادِ ٱلتَّقۡوَىٰۖ وَٱتَّقُونِ يَٰٓأُوْلِي ٱلۡأَلۡبَٰبِ١٩٧

al-ḥaju ashhurun maʿlūmātun faman faraḍa fīhinna l-ḥaja falā rafatha walā fusūqa walā jidāla fī l-ḥaji wamā tafʿalū min khayrin yaʿlamhu l-lahu watazawwadū fa-inna khayra l-zādi l-taqwā wa-ittaqūni yāulī l-albābi

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.
