Surah Al-Ma'idah 5:40

أَلَمْ تَعْلَمْ أَنَّ ٱللَّهَ لَهُۥ مُلْكُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ يُعَذِّبُ مَن يَشَآءُ وَيَغْفِرُ لِمَن يَشَآءُ ۗ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ

Do you not know that to Allāh belongs the dominion of the heavens and the earth? He punishes whom He wills and forgives whom He wills, and Allāh is over all things competent.

Translation: Saheeh International
