´Abu Hurairah narrated that The Messenger of Allah said:` “The most complete of the believers in faith, is the one with the best character among them. And the best of you are those who are best to your women.”
Narrated Abu Hurairah: The Prophet ﷺ said: The most perfect believer in respect of faith is he who is best of them in manners.
Shaykh Umar Farooq Saeedi
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.
