Quran 2, Al-Baqara (The Cow) ⓘ

2:197The pilgrimage is (in) the well-known months, and whoever is minded to perform the pilgrimage therein (let him remember that) there is (to be) no lewdness nor abuse nor angry conversation on the pilgrimage. And whatsoever good ye do Allah knoweth it. So make provision for yourselves (Hereafter); for the best provision is to ward off evil. Therefore keep your duty unto Me, O men of understanding.

الْحَجُّ أَشْهُرٌ مَعْلُومَاتٌ فَمَنْ فَرَضَ فِيهِنَّ الْحَجَّ فَلَا رَفَثَ وَلَا فُسُوقَ وَلَا جِدَالَ فِي الْحَجِّ وَمَا تَفْعَلُوا مِنْ خَيْرٍ يَعْلَمْهُ اللَّهُ وَتَزَوَّدُوا فَإِنَّ خَيْرَ الزَّادِ التَّقْوَى وَاتَّقُونِ يَا أُولِي الْأَلْبَابِ
