Mirza Shirazi and the Babi and Baha’i Faiths

Mirza Mohammad Hasan Hosseini Shirazi (The jurist and great authority of Shia Societies during Qajar time) has been mentioned many times in the historical texts of Babi and Baha'i. What is examined here is their statement about his family relation with Ali Mohammad Bab. Also, we study if his faith based on Bab's invitation, which is sometimes referred to as the secret faith of Babi and sometimes with the secret faith of Baha'i. This research is disassociated with the second view (the secret faith by the invitation of Bab and Bahaullah).
