Lutfu'llah Muhandis, the brother of Atā'ullāh Rashīdī (c. 1634) and the second son of Ustad Aḥmad, was also well-known for his interest in mathematics and other sciences. His *Muntakhab* is a short versified translation of Bahā'ud-dīn Āmuli's mathematical work *Khulāṣatu'l Ḥisāb* and was written in Persian in 1681 A. D. The copies of the manuscripts are available in the Asiatic Society of Bengal, Bankipur, British Museum, Azad Library (Aligarth) and Salarjang Library (Hyderabad). His *Risāla dar Jawāb i-Sawali* on geometry in question answer form and *Risāla-i-Arsmatiqi* on properties of numbers are still available in the Rampur Library and Saidiyah Library (Hyderabed). He wrote *Taqwim Luṭifi*, on almanac and *Tarjuma Kitāb Suwar-i-Kawakib*, a commentary on the celebrated astronomical work *Suwaru'l Kawākib*. The manuscript is available in Rampur Rida Library (U. P.) and Azad Library (Aligarh).
