Ajam
During the early age of the Caliphates, Ajam was often synonymous with "foreigner" or "stranger".  In the Western Asia, it was generally applied to the Persians, while in al-Andalus it referred to speakers of Romance languages - becoming "Aljamiado" in Spanish in reference to Arabic-script writing of those languages - and in West Africa refers to the Ajami script or the writing of local languages such as Hausa and Fulani in the Arabic alphabet.  In Zanzibar ajami and ajamo means Persian which came from the Persian Gulf and the cities of Shiraz and Siraf. In Turkish, there are many documents and letters that used Ajam to refer to Persian.
