Mírzá Hádí Qazvíní was the fifteenth Letter of the Living. He was the brother of Mírzá Muhammad-‘Alí Qazvíní. He was the son of Mulla ‘Abdu’l-Vahhab-i-Qazvini. He distanced himself from the Bábís and played no important role.
He was the recipient of several letters from Bahá’u’lláh; and became a follower of Mírzá Yahyá (Azal); some lists replace him with Mullá Muhammad Miyámayí, who actively propagated the new religion in Mayámey (Miyámay), a small town and district near Shāhrūd in northeastern Iran.
