The Kitáb-i-Aqdas - The Most Holy Book
Index term: Street, muttering sacred verses in
k108.
To none is it permitted to mutter sacred verses before the public gaze as he walketh in the street or marketplace; nay rather, if he wish to magnify the Lord, it behoveth him to do so in such places as have been erected for this purpose, or in his own home. This is more in keeping with sincerity and godliness. Thus hath the sun of Our commandment shone forth above the horizon of Our utterance. Blessed, then, be those who do Our bidding.

This is an allusion to the practice of certain clerics and religious leaders of earlier Dispensations who, out of hypocrisy and affectation, and in order to win the praise of their followers, would ostentatiously mutter prayers in public places as a demonstration of their piety. Bahá'u'lláh forbids such behaviour and stresses the importance of humility and genuine devotion to God.
