‘Abdu’l-Bahá in one of His Tablets has stated:
“Disposition of the Ḥuqúq, wholly or partly, is
permissible, but this should be done by permission of the authority in
the Cause to whom all must turn.” The provision in His Will and
Testament that the Ḥuqúqu’lláh “is to be offered
through the Guardian of the Cause of God…” is clearly in accord with
this principle. In another Tablet ‘Abdu’l-Bahá referred
to the Universal House of Justice as “the authority in the Cause to whom
all must turn” and it is clear that in the absence of the Guardian it is
the supreme and central institution of the Cause. Moreover, before
‘Abdu’l-Bahá, Bahá’u’lláh had revealed
the following: “There is a prescribed ruling for the
Ḥuqúqu’lláh. After the House of Justice hath come into
being, the law thereof will be made manifest, in conformity with the
Will of God.” In accordance with these explicit texts it is clearly
within the jurisdiction of the Universal House of Justice to decide
about the receipt and disbursement of Ḥuqúqu’lláh at
the present time.
