Quran 2:216

كُتِبَ عَلَيۡڪُمُ ٱلۡقِتَالُ وَهُوَ كُرۡهٌ۬ لَّكُمۡ‌ۖ وَعَسَىٰٓ أَن تَكۡرَهُواْ شَيۡـًٔ۬ا وَهُوَ خَيۡرٌ۬ لَّڪُمۡ‌ۖ وَعَسَىٰٓ أَن تُحِبُّواْ شَيۡـًٔ۬ا وَهُوَ شَرٌّ۬ لَّكُمۡ‌ۗ وَٱللَّهُ يَعۡلَمُ وَأَنتُمۡ لَا تَعۡلَمُونَ ٢١٦

Fighting may be imposed on you, even though you dislike it. But you may dislike something which is good for you, and you may like something which is bad for you. ALLAH knows while you do not know.
