Sirāj ud-Dīn Muhammad ibn Muhammad ibn 'Abd ur-Rashīd Sajāwandī (Persian: محمد ابن محمد ابن عبدالرشید سجاوندی) also known as Abū Tāhir Muhammad al-Sajāwandī al-Hanafī (Arabic: ابی طاهر محمد السجاوندي الحنفي) and the honorific Sirāj ud-Dīn (سراج الدین, "lamp of the faith") (died c. 1203 CE or 600 AH)[1] was a 12th-century Hanafi scholar of Islamic inheritance jurisprudence, mathematics[2] astrology and geography.
[3] He is primarily known for his work Kitāb al-Farāʼiḍ al-Sirājīyah (Arabic:کتاب الفرائض السراجیه), commonly known simply as "the Sirājīyah", which is a principal work on Hanafi inheritance law.
[2][4] The work was translated into English by Sir William Jones in 1792 for subsequent use in the courts of British India.
He lies buried in the Ziārat-e Hazrat-o 'Āshiqān wa Ārifān in Sajawand.
