Ibn 'Abbas said, "I do not know anyone who acts by this ayat: 'Mankind! We created you from a male and a female, and made you into peoples and tribes so that you might come to know each other. The noblest among you in Allah's sight is the one with the most taqwa.' (49:13) One man says to another man, 'I am more noble than you are.' No one is nobler than another person except by taqwa."
