“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

August 17

And likewise, He saith: “And had We sent down unto Thee a Book written on parchment, and they had touched it with their hands, the infidels would surely have said ‘This is naught but palpable sorcery.’” [Qur’án 6:7] Most of the verses of the Qur’án are indicative of this theme. We have, for the sake of brevity, mentioned only these verses. Consider, hath anything else besides the verses been established in the whole Book, as a standard for the recognition of the Manifestations of His Beauty, that the people might cling to, and reject the Manifestations of God? On the contrary, in every instance, He hath threatened with fire those that repudiate and scoff at the verses, as already shown.
