Abū al-Thanā’ Shihāb ad-Dīn Sayyid Maḥmūd ibn ‘Abd Allāh al-Ḥusaynī al-Ālūsī al-Baghdādī (Arabic: أبو الثناء شهاب الدين سيد محمود بن عبد الله بن محمود الحسيني الآلوسي البغدادي; 10 December 1802 – 29 July 1854 CE) was an Iraqi Islamic scholar best known for writing Ruh al-Ma`ani, an exegesis (tafsir) of the Qur'an.
He sent his tafsir to the authorities in Istanbul as proof for his loyalty to the established Islamic tradition and the Ottoman Empire.
[10] ʿĀrif Hikmet Bey was impressed by al-Alusis' deep knowledge and advised him to consult Reşid Mehmed Pasha for his concern.
Reşid Mehmed Pasha eventually assigned him as a member of the madrasa of the Murjan Mosque and the position of a mufti.
He died on 5 Dhul-Q'dah, 1270 AH (29 July 1854)[6] An exhaustive list of all his works far too long and thus difficult to compile.
