Kerman province is home to ethnic Persians, the absolute majority of them have been forced to Shi’ism during Safavid onslaught in 16th century. Today, a minority (mainly Baloch tribes) is Sunni (Hanafi), mainly in the south of the province.
Major Muslim-Sunni authorities and Imams in Fiqh, Aqidah, Hadith, Tafsir, Arabic (grammar, poetry etc.) uses to emerge from the famous Kerman region of the Persian lands.
As for Post-Safavid Persia, Kerman province i.e. today Shi’ite Iran: It has produced all those ‘great Ayatollahs’, known for superstitions, heresies and certainly ANYTHING but mastery of the Qur’an and Arabic, the likes of Rafsanjani and criminals like Qasem Soleimani, wallahu Al-Musta’an!
