Mu'ayyad al-Din Abu Isma'il al-Husayn ibn Ali ibn Muhammad ibn Abd al-Samad al-Du'ali al-Kināni al-Tughra'i (Arabic: العميد فخر الكتاب مؤيد الدين أبو إسماعيل الحسين بن علي بن محمد بن عبد الصمد الدؤلي الكناني الطغرائي) (1061 – c. 1121) was a poet and alchemist.^[1]

Mu'ayyad al-Din al-Tughra'i was born in Isfahan, Persia, and composed poems in the Arabic language. He was an administrative secretary (therefore the name Tughra'i'). He ultimately became the second-most-senior official (after the vizier) in the civil administration of the Seljuq Empire.^[2]

Al-Tughra'i had been appointed vizir to Emir Ghiyat-ul-Din Mas'ud, and upon the death of the emir a power struggle ensued between Mas'ud's sons. Al-Tughra'i sided with the emir's elder son, but the younger prevailed. In retribution, the younger son accused al-Tughra'i of heresy and had him beheaded.^[2]

Al-Tughra'i was a well-known and prolific writer on astrology and alchemy, and many of his poems (diwan) are preserved today as well. In the field of alchemy, al-Tughra'i is best known for his large compendium titled Mafatih al-rahmah wa-masabih al-hikmah, which incorporated extensive extracts from earlier Arabic alchemical writings, as well as Arabic translations from Zosimos of Panopolis's old alchemy treatises written in Greek, which were until 1995 erroneously attributed to unknown alchemists by mistakes and inconsistencies in the transliteration and transcription of his name into Arabic.^[3]

In 1112 CE, al-Tughra'i also composed Kitab Haqa'iq al-istishhad, a rebuttal of a refutation of the occult in alchemy written by Ibn Sina.
