أَلَمْ تَعْلَمْ أَنَّ ٱللَّهَ لَهُۥ مُلْكُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ يُعَذِّبُ مَن يَشَآءُ وَيَغْفِرُ لِمَن يَشَآءُ ۗ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ
5:19; 48:15.
Commentary:
Expressions like, He punishes whom He pleases and forgives whom He pleases, do not mean that the divine government of the universe is arbitrary and is based on no system or law. Such expressions are only intended to point out that, God being the final authority in the universe, His word is the law, there being no appeal against His orders. So man should be extremely careful in following His wish and carrying out His commandments. But, as God has Himself ordained, "His mercy surpasses or outweighs His anger" (Bukhari), and the universe is governed by "set laws of good and evil" (Muslim, ch. on Iman).
