What follows is my provisional translation (in other words, not official or authorized; see here for more) of a prayer of Baháʼuʼlláh, the original text of which has been published in Adʻíyyiy-i-Ḥaḍrat-i-Maḥbúb, pp. 362–63.
He is the Helper, the Giver of victory
My God, the Most Generous, the Most Compassionate! I have turned my face unto Thee, holding fast to the cord of Thy loving-kindness and clinging to the hem of Thy munificence. Thou art that All-Bountiful One a single drop from the ocean of Whose pardon washeth away all the world’s sins, and one word from the mouth of Whose grace bestoweth the water of life unto all humanity.
O peerless Giver! Deprive not Thy servant; grant him a portion from the ocean of Thy mercy, and ordain for him a share from the sea of Thy generosity. The tongues of the world are not fit to render Thee praise, and the hearts of men are unworthy of apprehending Thy reality, which hath ever lain beyond the comprehension of their minds and transcended the ken of their understanding. In a state of utmost helplessness and ardent supplication, I beseech Thine ancient grace and seek Thine all-pervasive bounty. Thou art well aware that I am alive through Thy praise, and that I exist through the hope of standing in Thy presence. Do that which beseemeth Thy grace, not what befitteth my glorification of Thee.
No God is there but Thee, the Ever-Forgiving, the Most Generous. Praise be unto Thee; Thou art the Goal of every searching soul.
