Notes (Tafseer)

6163. The good are distinguished here by three signs: (1) large-hearted sacrifices for Allah and men: (2) fear of Allah, which shows itself in righteous conduct for Taqwa, (see n. 26 to ii. 2) includes just action as well as a mental state: and (3) truth and sincerity in recognising and supporting all that is morally beautiful, for Husn is the good as well as the beautiful.
