Roz 7 Māh 2 (Kadmī) 1200 Yazdegerdi.

Death: Mullā Firoz son of Mullā Kāus. Age: 72. The eldest son of Mullā Kāus Rustam Jalāl, and High Priest of the Bombay Kadmi Sect. At the age of 8, he had gone to Iran with his father in the year 1768 AD. Afterwards, having received a complete education in the Persian and Arabic languages there, he returned to Surat with his father in 1780 and came to Bombay. Having arrived here, in the year 1786, he wrote a description of his and his father's trip to Iran in Persian in book form named the Dīn-e [error for Dīn] Kherad-e Manzūme [For Persian دین خرد منظومه, Wisdom of the Religion Versified]. Afterwards, because Mullā Kāus went to Hyderabad in 1794, he attained the rank of High Priest of the Bombay Kadmi Sect. He spent his whole life writing books. He went to teach Bombay Governor Jonathan Duncan Persian at the monthly salary of 100 rupees, and with him, he began to work on the English translation of the book (entitled) Dasātīr; though three sections were completed, because that famous Governor died in the year 1811 AD, the rest of the work remained incomplete, so he had Mr. William Erskine complete it, and had it published in 1819 AD. After publishing this translation, many Englishmen quarreled violently, saying, “This book was produced through forgery!” At that time, he wrote long letters with much intelligence in the Bombay Courier in response to these quarrels. Since the time of Governor Duncan himself, just as Ferdosi's, the poet of the history of the kings of Iran's, Shāhnāma, had been written in Persian verse, corresponding to that, he had begun to create a book called the Georgenāma concerning the Englishmen's conquest and history in India. Having petitioned the government for support, on the first of October, 1828, the government awarded him a monthly salary of rupees 400 for his life's work. Because the work was not finished when he passed away, after his death, his nephew and heir to his position, Dastur Rustamji Kekobaji, printed it and put it out in three volumes.

From 1826-27, he was the chief leader of the Kadmis in a quarrel in Bombay relating to the intercalation and an instigator of the quarrel, and at that time, he incurred a great loss with regard to money. He was also made a leader (akābar) of the Parsi Panchayat at that time. Before his death, he gave over his valuable library, in which there were Persian, Arabic, Turkish, astronomical, as well as Zend, Pazend, Pahlavi, and English books, by his own writing to the control of the Trustees of the Kadmi Anjuman, saying “Our heirs should take no trouble regarding this library, and this library should be kept publicly in our name for all the knowledgeable people of the community to read.” According to this will, after his death, a list was prepared by Mobed Fardunji Marzubānji, and under the supervision of the Kadmi leaders, the “Mullā Firoz Library” was opened for all people to (come and) read. Likewise, in 1854, on the occasion of the death of the heir to his position, Dastur Rustamji Kekobādji, the Zoroastrians here founded a school as a memorial in his name called the "Mullā Fīroz Madresā" to teach the sons of Zoroastrians Zend, Pahlavi, and Persian.
