What follows is my provisional translation (in other words, not official or authorized; see here for more) of a passage from a Tablet of Bahá’u’lláh, the original text of which has been published in Áyát-i-Bayyinát, p. 102 (selection no. 90).
Let nothing grieve thee. He, verily, is the Helper of whosoever turneth unto Him and trusteth in Him.
A typescript of the original Arabic text of this passage appears below (all punctuation and short vowel marks mine).
