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

July 15

O ‘Alí-Akbar! Acquaint the people with the holy verses of thy Lord and make known unto them His straight Path, His mighty Announcement.

Say: O people, if ye judge fairly and equitably, ye will testify to the truth of whatsoever hath streamed forth from the Most Exalted Pen. If ye be of the people of the Bayán, the Persian Bayán will guide you aright and will prove a sufficient testimony unto you; and if ye be of the people of the Qur’án, ponder ye upon the Revelation on Sinai and the Voice from the Bush which came unto the Son of ‘Imrán [Moses].

Gracious God! It was intended that at the time of the manifestation of the One true God the faculty of recognizing Him would have been developed and matured and would have reached its culmination. However, it is now clearly demonstrated that in the disbelievers this faculty hath remained undeveloped and hath, indeed, degenerated.
