بسم الله الرحمن الرحيم

وَعَسَىٰٓ أَن تَكۡرَهُواْ شَيۡـًٔا وَهُوَ خَيۡرٌ لَّكُمْۖ وَعَسَىٰٓ أَن تُحِبُّواْ شَيۡـًٔا وَهُوَ شَرٌّ لَّكُمْۗ وَٱللَّهُ يَعۡلَمُ وَأَنتُمۡ لَا تَعۡلَمُونَ

and it may be that you dislike a thing which is good for you and that you like a thing which is bad for you. Allah knows but you do not know. (2:216)

Al-Allaamah al-Uthaymeen (rahimahullah):

Do not dislike something which Allah has chosen (decreed), for indeed Allah has chosen something which has a tremendous benefit in it, you are just not aware of it!
