Index term: recitation of verses, under Morning
k149.
Recite ye the verses of God every morn and eventide. Whoso faileth to recite them hath not been faithful to the Covenant of God and His Testament, and whoso turneth away from these holy verses in this Day is of those who throughout eternity have turned away from God. Fear ye God, O My servants, one and all. Pride not yourselves on much reading of the verses or on a multitude of pious acts by night and day; for were a man to read a single verse with joy and radiance it would be better for him than to read with lassitude all the Holy Books of God, the Help in Peril, the Self-Subsisting. Read ye the sacred verses in such measure that ye be not overcome by languor and despondency. Lay not upon your souls that which will weary them and weigh them down, but rather what will lighten and uplift them, so that they may soar on the wings of the Divine verses towards the Dawning-place of His manifest signs; this will draw you nearer to God, did ye but comprehend.

Recite ye the verses of God every morn and eventide.
Bahá'u'lláh states that the essential "requisite" for reciting "the verses of God" is the "eagerness and love" of the believers to "read the Word of God" (Q&A 68).
With regard to the definition of "verses of God", Bahá'u'lláh states that it refers to "all that hath been sent down from the Heaven of Divine Utterance". Shoghi Effendi, in a letter written to one of the believers in the East, has clarified that the term "verses of God" does not include the writings of 'Abdu'l-Bahá; he has likewise indicated that this term does not apply to his own writings.

Question: Concerning the sacred verse: "Recite ye the verses of God every morn and eventide."
Answer: The intention is all that hath been sent down from the Heaven of Divine Utterance. The prime requisite is the eagerness and love of sanctified souls to read the Word of God. To read one verse, or even one word, in a spirit of joy and radiance, is preferable to the perusal of many Books.
