Your criterion should be to pursue your commercial activities with such fairness and equity as to be a cause of guidance to others. The friends of God should, through the instrumentality of their business, lead the people to God's path, and make them so astonished as to exclaim: "How great is their truthfulness, how high their trustworthiness, and how true is their good will!" (‘Abdu’l-Baha, from a Tablet; The Compilation of Compilations, vol. I, Trustworthiness: A Cardinal Bahá'í Virtue)
