Qur'an 2:216 · Al-Baqara

كُتِبَ عَلَيْكُمُ ٱلْقِتَالُ وَهُوَ كُرْهٌۭ لَّكُمْ ۖ وَعَسَىٰٓ أَن تَكْرَهُوا۟ شَيْـًۭٔا وَهُوَ خَيْرٌۭ لَّكُمْ ۖ وَعَسَىٰٓ أَن تُحِبُّوا۟ شَيْـًۭٔا وَهُوَ شَرٌّۭ لَّكُمْ ۗ وَٱللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ

(216) 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.
