written in Samarqand in 1892; among its subjects, it discusses the traditions in Shia Islam regarding the persecution of the Promised One. The book was written in reply to an attack by an Adharbayjan Shia cleric. No known copy of the work exists. Risaliyyih Iskandaraniyyih: Published along with Al-Duraru'l-Bahiyyih, the paper provides proofs for Muhammad's prophethood from Christian and Jewish scripture. It also explains the verse from the Qurʼan "Then it is ours to explain it." The Kitab-i-Ibrar (Book of Justification): While no manuscript of this book currently exists, it was referred to in Abu'l-Faḍl's other works and seems to have dealt with the Covenant. Al-Hujaju'l-Baháʼíyyih (The Baháʼí Proofs): A book written while in the United States, which explains and defends the Baháʼí Faith from a Christian point of view. Kashfu'l-Ghita (The Uncovering of Error): After E.G. Browne published the Nuqtatu'l-Kaf, which was hostile to the Baháʼí Faith, Abu'l-Faḍl began working on refutations of that book. When he learned that other Baháʼí scholars had also started working on refutations that had reached an advanced stage, he suspended his writing. He never completed the book, and when his papers were sent to his cousin in Ashkhabad, his cousin worked on completing the book, of which 132 of 438 pages are written by Abu'l-Faḍl. Letters In addition to the books that Abu'l-Faḍl wrote, he also wrote a number of shorter works in response to questions addressed to him; some of these letters have been published in a number of compilations: Majmuʻiy-i-Rasaʼil-i-Hadrat-i-Abi'l-Faḍl: Published in Cairo in 1920 and contains 16 letters and treatises. Rasa'il wa Raqa'im: Published in Persian in Tehran in 1977, and contains 23 treatises and 59 letters. Some of the treatises from this work have been translated by Juan Cole into English in Letters & Essays including: Two treatises on the Covenant: Published in 1911 in Cairo consisting of two treatises written in 1899 and 1896 which deal with proofs from the Bible and the Qurʼan, and about the actions of Covenant-breakers. Risalih Iskandariyyih (Treatise of Alexander): Written in response to a request by E.G. Browne to write about the life of Baháʼu'lláh among other things. The letter was named in honour of Alexander Tumansky, who had also requested information about Baháʼu'lláh. Al-Bab wa'l-Babiyyih (The Báb and Bábísm): A brief history of the Baháʼí Faith commissioned by the editor of the Egyptian magazine Al-Muqtataf after the assassination of Nasser al-Din
