According to the "Kashfu'l-Ghiti'" (p. 110), Mulla Husayn is reported by Mulla Ja'far-i-Va'iz-i-Qazvini to have met Tahirih in Qazvin at the home of Aqa Hadi, who is probably none other than Muhammad Hadiy-i-Farhadi, who was commissioned by Baha'u'llah to conduct Tahirih to Tihran. The meeting is stated to have taken place prior to the murder of Mulla Taqi.
