What follows is my provisional translation (in other words, not official or authorized; see here for more) of a prayer of ‘Abdu’l-Bahá for Ḥájí Mihdí Námí, the original text of which has been published in Makátíb-i-Ḥaḍrat-i-‘Abdu’l-Bahá, vol. 6, pp. 143–44. I was also supplied this facsimile of the original text, written in the hand of ‘Abdu’l-Bahá, by Lili Mahvash, the great-granddaughter of Ḥájí Mihdí Námí.
To the pilgrim, Áqá Mihdí, son of Áqá Yárí, upon him be the Glory of God, the All-Glorious
He is God
O God, my God! Thy servant, Mihdí, standeth before Thine exalted threshold, supplicating the celestial Kingdom and imploring aid from “the strong support” for himself, his wife, his mother, and all his kindred.
Lord! These souls have severed themselves from all else but Thee; they have championed Thy supporters and opposed those who have showed enmity towards Thee. Among Thy servants, they deserve Thine aid and are worthy of Thy grace and generosity. O Lord! Ease the fulfillment of their desire and amply bestow on them Thy bounty. Lift the veil from before their sight and intoxicate them with the wine of Thy favors.
Pardon Thou his father, who hath ascended unto Thee and entered into Thy presence with a heart hopeful and humble before Thee. O Lord! Grant him a cup “tempered at the camphor fountain,” cleanse him with the limpid waters of Paradise, and immerse him in oceans of light. Thou, verily, art the Pardoner, the Forgiver.
O God! Make his sons glorious, his sons-in-law righteous, and all his kindred pure. Do Thou assist them night and day by Thy grace. Behold them all, O Lord, with the glances of Thy tender care and the eye of Thy loving-kindness, Thy grace, and Thy mercy. Fortify well for them the way of growth, and keep them safe and secure from the path of error. Rend thou the veils asunder and cause the clouds to send down their rain. Provide them with means in this world, and submerge them in the seas of pardon and forgiveness that lie in the Kingdom of mysteries.
Thou, in truth, art the Most Generous, the Most Merciful, the Almighty, the Ever-Forgiving.
