Surah Al-Baqara, Verse 197
ٱلْحَجُّ أَشْهُرٌۭ مَّعْلُومَٰتٌۭ ۚ فَمَن فَرَضَ فِيهِنَّ ٱلْحَجَّ فَلَا رَفَثَ وَلَا فُسُوقَ وَلَا جِدَالَ فِى ٱلْحَجِّ ۗ وَمَا تَفْعَلُوا۟ مِنْ خَيْرٍۢ يَعْلَمْهُ ٱللَّهُ ۗ وَتَزَوَّدُوا۟ فَإِنَّ خَيْرَ ٱلزَّادِ ٱلتَّقْوَىٰ ۚ وَٱتَّقُونِ يَٰٓأُو۟لِى ٱلْأَلْبَٰبِ
Translation — Sahih International
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.
