Bahá’u’lláh counsels Sultán ‘Abdu’l-‘Azíz “not forgetful of the law of God”

Be not forgetful of the law of God in whatever thou desirest to achieve, now or in the days to come. Say: Praise be to God, the Lord of all worlds!” 

- Baha’u’llah  (Quoted by Shoghi Effendi in ‘The Promised Day Is Come’)
