It is not possible to accept a free grant of land from the government to be used as a Temple site. The principle of not accepting gifts from non-Bahá'ís for strictly Bahá'í purposes applies to receiving free grants of land from non-Bahá'ís, whether individuals, institutions, or governments. There is no objection, however, to accepting free plots of land from the government or civic authorities if such plots are used for Bahá'í cemeteries or such institutions that are charitable or humanitarian in nature, such as schools.
