Epistle to the Son of the Wolf

[2][3] Baháʼu'lláh called the father, Shaykh Muhammad Báqir (1819-1883),[2] the Wolf because of his responsibility for the execution of the Nahrí brothers in Isfahan in 1879.

After confronting Shaykh Muhammad-Baqir and Sultán-Mas'úd Mírzá, the son of Násiri'd-Dín Sháh of this issue, the three devised a plan to imprison the brothers on account of their Baháʼí Faith.

One such tablet, Lawh-i-Burhán, addressed to Shaykh Muhammad Báqir accuses him and his accomplice Mír Muḥammad Ḥusayn of the persecution of the Baháʼís.

In this book Baháʼu'lláh described historical events such as His "arrest in Níyávarán and of the kind of chains that bound Him and of the machinations against Him by members of the Persian embassy in Constantinople.

[3] He also wrote about his suggestion to Kamál Páshá, a Turkish official, that his government convene a gathering to plan for a world language and script.
