Wikipedia:Manual of Style/Bahá'í spelling

Baháʼí spelling is used for expressions and names if all four of following conditions are met:

  1. The expression or name is found with that spelling in the glossary at the bahai.org website, currently https://news.bahai.org/media-information/style-guide/ – or whatever updated digital version of that guide, if it uses unicode characters and is accepted as such by consensus
  2. The spelling is not explicitly forbidden by the WP:AT policy
  3. The expression or name is only, or nearly only, used in connection with Baháʼí Faith (i.e. it has no common or widespread usage outside that Faith)
  4. Single quotation marks (e.g. ) and curly apostrophes (e.g. ) are routinely converted to the straight (simple) apostrophe character (') per general WP:MOS recommendations.

Note that various Baháʼí words and proper names, such as Baháʼí Faith, Baháʼu'lláh and Ḍíyáʼu'lláh, are properly written with a modifier letter apostrophe after the letter a, as defined by the glossary in the 1st condition, and used primarily for glottal sounds; thus, this glottal ʼ does not meet the 4th condition's single quotation marks nor curly apostrophes requirement.

For usage of the expression or name as (or: in) an article title there is a fifth condition:

  1. redirects from all common simpler and/or more complex variant spellings of the expression or name should be existing

Examples:

  • "children's classes", not "children’s classes" (found in glossary, but fails 3rd and 4th conditions).
  • The routine conversion mentioned in the 4th condition only applies to single quotation marks and curly apostrophes, thus:
    • Winters, Jonah (Winter 1999). "Review (of) Symbol and Secret: Qur'án Commentary in Baháʼu'lláh's Kitáb-i Íqán by Christopher Buck (and of) Revisioning the Sacred: New Perspectives on a Baháʼí Theology by Jack McLean". Iranian Studies. 32 (1). Taylor & Francis: 141–145. JSTOR 4311219.
and not:
Qur'án and Kitáb-i Íqán are quoted as in the title of the journal article, not adapted to the spelling of Wikipedia's article titles (Quran and Kitáb-i-Íqán respectively), per MOS:PMC.
