Lisan ud-Dawat
Lisaan ud-Da'wat or Lisaan o Da'wat il Bohra or Lisan ud-Dawat (Arabic: لسان الدعوة, lit. 'language of the Da'wat', da'wat ni zabaan; abbreviated LDB) is the language of the Dawoodi Bohras and Alavi Bohras, Isma'ili Shi'a offshoots of the Muslim community primarily from Gujarat, who follow the Taiyebi doctrines and theology. The language is based on a Neo-Indo-Aryan language, Gujarati, but incorporates a heavy amount of Arabic, Urdu, and Persian vocabulary and is written in the Arabic script naskh style.
