أَلَمْ تَعْلَمْ أَنَّ ٱللَّهَ لَهُۥ مُلْكُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ يُعَذِّبُ مَن يَشَآءُ وَيَغْفِرُ لِمَن يَشَآءُ ۗ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌۭ
Knowest thou not that unto Allah belongeth the Sovereignty of the heavens and the earth? He punisheth whom He will, and forgiveth whom He will. Allah is Able to do all things.
