If thou desirest to be freed from affliction, recite thou this prayer which hath been revealed by the Pen of the All-Merciful:
“O God, my God! I testify to Thy unity and to Thy oneness. I beseech Thee, O Thou Possessor of names and Fashioner of the heavens, by the pervasive influence of Thine exalted Word and the potency of Thy supreme Pen, to aid me with the ensigns of Thy power and might, and to protect me from the mischief of Thine enemies who have violated Thy Covenant and Thy Testament. Thou art, verily, the Almighty, the Most Powerful.”
This invocation is an impregnable stronghold and an indomitable army. It conferreth protection and ensureth deliverance.
(Baha’u’llah, ‘The Tabernacle of Unity, Bahá’u’lláh’s Responses to Mánikchí Sáhib and Other Writings’)
