The Priceless Pearl, Ruhiyyih Khanum, p275-6
As I am compelled to leave Haifa for reasons of health, I have named as my representative during my absence, the sister of 'Abdu'l-Bahá, Bahiyyih Khanum . . . To assist her to conduct the affairs of the Bahá'í Movement in this country and elsewhere, I have also appointed a committee of the following Bahá'ís [eight men of the local community, three of them the sons-in-law of 'Abdu'l-Bahá]...The Chairman of this Committee, to be soon elected by its members, with the signature of Bahiyyih Khanum has my authority to transact any affairs that may need to be considered and decided during my absence. I regret exceedingly to be unable to see you before my departure, that I may express more adequately the satisfaction that I feel to know that your sense of justice will safeguard the interests of the Cause of Bahá'u'lláh whenever called upon to act.
