Sadiduddin Muhammad Aufi (1171-1242) (Arabic: سدید الدین محمد عوفی) was a Persianhistorian, scientist, and author.
Born in Bukhara, Aufi grew up during the apex of the Islamic Golden Age and spent many years traveling, exploring, and lecturing to the common folk and the royalty alike in Delhi, Khorasan, Khwarizm, Samarkand, Merv, Neishaboor, Sistan and Ghaznayn. He spent most of his time at the courts of Ghaurid kings. He dedicated his first grand work Lubab ul-Albab, which consisted of poems by kings and poets of ancient times, to the vizier of the Ghaurid Amir Nasiriddin Ghobajeh (ناصر الدین قباجه) (d. 1227).
His second magnum opus Jawami ul-Hikayat was written under the name of the Vizier of the Ghurid Amir of Delhi. He lived during the reign of Shamsuddin Iltutmish (Altamash) (r. 1211–1236) who was the third Muslim Turkic sultan of the Sultanate of Delhi, and the book is dedicated to his minister, Nizam-ul-Mulk Muhammad, son of Abu Sa'id Junaidi. These two are the only remaining works from him today. His works on The History of Turkistani Lords, and his book On the Properties of Matter, both referenced elsewhere, do not exist anymore. A small fragment of his Madayih al-Sultan remains.
