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 is published in Adʻíyiy-i-Ḥaḍrat-i-Maḥbúb, pp. 358–59.
This Wronged One imploreth pardon on behalf of everyone, saying:
O God, my God! Protect Thy loved ones. Thou art that Bountiful One Whose forgiveness hath encompassed the world. Have mercy on Thy servants, and confirm those deeds, behaviors, and sayings which beseem Thy days. With one exalted Word, the Ocean of Thy beneficence hath surged, and with a single effulgence from the Day-star of Thy Revelation, the Sun of Thy generosity and pardon is resplendently manifest. All are Thy servants and live in hope of Thy munificence. Draw forth the hand of power from the bosom of might, and rescue these mired souls. Thou art the Sovereign of volition, the King of grace. No God is there but Thee, the Almighty, the All-Bounteous.
