Baháʼu'lláh's proclamation in 1863. After Baháʼu'lláh's further banishment, Mustafá was recognized as a leader among the Baháʼís in Iraq and sought after for help. In 1867, 53 Baháʼís of Baghdad wrote an appeal to the Congress of the United States for assistance in freeing Baháʼu'lláh from confinement by Ottoman authorities. This appeal arrived at the American Consul in Beirut and was commented upon by American missionary Henry Harris Jessup. Beginning in 1868, and instigated by conversions of Sunni Muslims to the Baháʼí Faith, the Baháʼís of Baghdad were arrested and imprisoned repeatedly. In April–May 1868, three or four Baháʼís of Baghdad were killed by Persian Shias, likely offended by Baháʼís celebrating holy days during their mourning ceremonies. In 1872, Mustafá was attacked by an angry mob and nearly killed. Two years later he spent eight months in prison, along with many other Baháʼís of Baghdad. Upon his release in 1874, he traveled to ʻAkká and Baháʼu'lláh instructed him to move to Beirut. While in Beirut he was the main conduit for coordinating Baháʼí pilgrims on their way to Palestine. Mustafá became the liaison between the Ottoman political authorities and the Baháʼís, and his home became a meeting place of dignitaries such as the mufti and ʻAbdu'l-Bahá's family. For decades, he was the focal point of internal and external communications. The "facilities provided by [Baha'u'llah's] staunch follower, Muhammad Mustafá, now established in Beirut to safeguard the interests of the pilgrims who passed through that city" was listed by Shoghi Effendi as one several milestones that attested to the vitality of the religion toward the end of Baháʼu'lláh's life. His home in Beirut was host to the remains of the Báb for twelve days in January 1899, as they made their way secretly from Persia to ʻAkká, via Baghdad, Damascus, and Beirut. The casket was carried by hand by Mustafá and seven others from Beirut to ʻAkká, arriving 31 January 1899. After the passing of Baháʼu'lláh in 1892, he served as ʻAbdu'l-Bahá's representative in Beirut. As he got older, his eyesight began to fail. In 1910 he moved north to Alexandretta (Iskandarun) where he died soon after. Legacy Mustafá wrote a chronicle of the Bábí movement, ar-Risalah al-Amriyyah (The Treatise on the Cause), that was appended to Ar-Risalah at-Tis` `Ashariyyah (The Treatise of Nineteen) by Ahmad Sohrab. The works were published in Cairo in 1919. Abbas Amanat wrote in Resurrection and Renewal
