Sadaf
Sadaf means 'seashell' or 'mother-of-pearl' and comes from Persian vocabulary used in names and poetry.
Sadaf is of Persian origin and is used in Persianate and Urdu-speaking Muslim communities; the root word also exists in Arabic as صَدَفَة/صدفة meaning 'shell'.
No. Sadaf is a cultural and literary name; it is not a Quranic or Prophetic name and does not appear in classical hadith collections as a personal name.
Common pronunciation in Persian and South Asian usage is 'SAH-daf' (stress on first syllable).
Similar poetic Persian female names include Shireen, Soraya, and Sedef (Turkish variant).
