Benefits and Issues: (Akhlaq) is the plural of khuluq, with a dhamma (u-sound) on the kha and lam. By this is meant a person’s habits and actions; excellent habits are described as the perfection of faith (iman). Whoever’s habits and dealings with others are improper, his faith is deficient to that extent.
