Mírzá Muḥammad Muṣṭafá al-Baghdádí (1837/8—1910) was a prominent Iraqi adherent of the Baháʼí faith and one of 19 Apostles of Baháʼu'lláh. Mustafá was among the leading Baháʼís in Iraq until he moved to Beirut in the late 1870s, where he coordinated pilgrims going to see Baháʼu'lláh in ʻAkká, and later he was involved with the movement of the Báb's remains to ʻAkká. As a child, his family hosted Táhirih in Baghdad and later accompanied her on a trip to Iran, where they met Mullá Husayn. Background and family Mustafá was the son of Shaykh Muhammad Shibl (a.k.a. Shaikh Mohammad Šebl) Baghdadi, a high-ranking ulama of the city. Mustafa's father, grandfather (Sayyed Darvish), great-grandfather (Sayyed Shebl), and great-great-grandfather (Sayyed Sharif Kazemi) were all theologians in Kufa, then his father moved to Baghdad in 1827-28, a decade before Mustafá was born, taking the role of teaching theosophy for Siyyid Kázim. Mustafá's father became Kázim's personal representative in Baghdád, and later became one of the first Shaykhi leaders to become a Bábí in the mid-1840s, having been taught by Mullá ʻAlíy-i-Bastámí (one of the Báb's Letters of the Living) when he was brought to Baghdád and imprisoned. He later attempted to meet the Báb in Iran, but due to the Báb's banishment to Azerbaijan, he went to Khurasan and met Quddús instead. Travel to Iran When Mustafá was nine years old, his family hosted Táhirih for about ten weeks in 1846, where she taught unveiled and enraged students by speaking of the need to abrogate the Sharia. Mustafá waited upon her and transmitted her messages in Baghdad and later Iran. The letter from the Báb bestowing the title Táhirih was read to a gathering of people at their home by Mustafá's father. When she was eventually expelled from Baghdád, Mustafá, his father, and about thirty armed men left with her to Iran in March 1847 on a trip paid for by Mustafá's family. They arrived in Kirmanshah, then Qazvin for one month, after which they separated from Táhirih and went to Tehran, at her request, to meet Mullá Husayn on his way to Mazandaran. They then returned to Baghdad, where his father died on 11 July 1850. Service to Baháʼu'lláh During the period that Baháʼu'lláh was in Baghdád (1853-1863), Mustafá became devoted to him and was among the few who recognized him as the Báb's prophesied He whom God shall make manifest, before
