One amongst His [Baha’u’llah’s] Teachings is this, that love and good faith must so dominate the human heart that men will regard the stranger as a familiar friend, the malefactor as one of their own, the alien even as a loved one, the enemy as a companion dear and close…The meaning is that they must treat all humankind even as they treat their sympathizers, their fellow-believers, their loved ones and familiar friends. 
- ‘Abdu’l-Baha  (‘Selections from the Writings of ‘Abdu’l-Baha’)
