Surah Al-Baqarah, Verse 216

كُتِبَ عَلَيۡكُمُ ٱلۡقِتَالُ وَهُوَ كُرۡهٞ لَّكُمۡۖ وَعَسَىٰٓ أَن تَكۡرَهُواْ شَيۡـٔٗا وَهُوَ خَيۡرٞ لَّكُمۡۖ وَعَسَىٰٓ أَن تُحِبُّواْ شَيۡـٔٗا وَهُوَ شَرّٞ لَّكُمۡۚ وَٱللَّهُ يَعۡلَمُ وَأَنتُمۡ لَا تَعۡلَمُونَ٢١٦

kutiba ʿalaykumu l-qitālu wahuwa kur'hun lakum waʿasā an takrahū shayan wahuwa khayrun lakum waʿasā an tuḥibbū shayan wahuwa sharrun lakum wal-lahu yaʿlamu wa-antum lā taʿlamūna

Battle has been enjoined upon you while it is hateful to you. But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allāh knows, while you know not.
