Sura al-Baqara 2:216

كُتِبَ عَلَيْكُمُ ٱلْقِتَالُ وَهُوَ كُرْهٌ لَّكُمْ وَعَسَىٰٓ أَن تَكْرَهُوا۟ شَيْـًٔا وَهُوَ خَيْرٌ لَّكُمْ وَعَسَىٰٓ أَن تُحِبُّوا۟ شَيْـًٔا وَهُوَ شَرٌّ لَّكُمْ وَٱللَّـهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ

kutiba ʿalaykumu l-qitālu wa-huwa kurhun la-kum waʿasa an takrahū shayʾan wa-huwa khayrun la-kum wa-ʿasa an tuḥibbū shayʾan wa-huwa sharrun la-kum wallāhu yaʿlamu wa-antum lā taʿlamūna

Fighting is prescribed for you, and ye dislike it. But it is possible that ye dislike a thing which is good for you, and that ye love a thing which is bad for you. But Allah knoweth, and ye know not.
