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

April 25

O people of the Bayán!  Would ye deny Him Whose presence is the very object of your creation, while ye rejoice idly upon your couches?  Would ye laugh to scorn and contend with Him, a single hair of Whose head excelleth, in the sight of God, all that are in the heavens and all that are on the earth? O people of the Bayán! Produce, then, that which ye possess, that I may know by what proof ye believed aforetime in the Manifestations of His Cause, and by what reason ye now wax so disdainful!

I swear by Him Who hath fashioned Me from the light of His own Beauty!  None have I ever seen that surpasseth you in heedlessness or exceedeth you in ignorance. Ye seek to prove your faith in God through such holy Tablets as ye possess, yet when the verses of God were revealed and His Lamp was lighted, ye disbelieved in Him Whose very Pen hath fixed the destinies of all things in the Preserved Tablet.  Ye recite the sacred verses and yet repudiate Him Who is their Source and Revealer. Thus hath God blinded your eyes in requital for your deeds, would ye but understand. Day and night ye transcribe the verses of God, and yet ye remain shut out, as by a veil, from Him Who hath revealed them. 

- Baha’u’llah  (Súriy-i-Haykal, ‘The Summons of the Lord of Hosts’)
