September 16

Once the validity of a divinely appointed Prophet hath been established, to none is given the right to ask why or wherefore. Rather is it incumbent upon all to accept and obey whatsoever He saith. This is that which God hath decreed in all His Books, Scriptures and Tablets. 
(Baha’u’llah, ‘The Tabernacle of Unity, Bahá’u’lláh’s Responses to Mánikchí Sáhib and Other Writings’)
