A Short Prayer of Baha’u’llah for Changing Hardship into Ease

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 Maṣábíḥ-i-Hidáyat, vol. 9, p. 562

He is God

O Lord! Change the hardship of Thy loved ones into ease. Turn their adversity into prosperity, their abasement into glory, and their sorrow into the most great joy, O Thou in Whose hand are the reins of all mankind. Verily, Thou art God, the Peerless, the Incomparable, the All-Powerful, the All-Knowing, the All-Informed.

A typescript of the Arabic text of this prayer appears below (vocalization not mine).

هوالله

أی رَبِّ بَدِّلْ عُسرَ أولیائِکَ بِالیُسْرِ وَ شِدَّتَهُم بِالرّخاءِ و ذُلَّهُم بِالعِزِّ و حُزنَهُم بالفَرَحِ الأکبرِ یا مَن بِیَدِکَ زِمامُ البَشَرِ إنَّکَ أنتَ اللهُ الفردُ الواحدُ المقتَدِرُ العلیمُ الخبیر.
