Abū Abd al-Raḥmān Abdallāh Ibn Lahīʿa ibn ʿUqba ibn Furʿān ibn Rabīʿa ibn Thawbān al-Ḥaḍramī al-Aʿdūlī (Arabic:أبوعبدالرحمن عبدالله بن لهيعة بن عقبة بن فرعان بن ربيعة بن ثوبان الحضرمي الأعدولي) (96–174AH) (714/5–790 AD) more commonly known asIbn Lahi'a (إبن لهيعة), was anArab historian, scholar ofhadith andQadi (قاضي;lit. 'judge') ofEgypt.^[1][2] Famed for being the first judge of Egypt to be appointed directly by a caliph.

Nothing is known about Ibn Lahi'a's early years of his life, except that he was probably born in Egypt in the year 714/5 to a family ofYemeni origin.^[1] As a historian and a collector of hadith, Ibn Lahi'a gained fame around Egypt, which at the time was part of theAbbasid Caliphate (750–1258). Due to his great reputation of being a respected learned man among his contemporaries, the Abbasid caliphal-Mansur (r. 754–775) personally appointed him to the position ofQadi of Egypt, which he occupied from 772 to 780.[1] The caliph also issued him a payment of 30dinars per month as a salary. He died in the year 790.^[2] According to the massive encyclopedic workSiyar A'lam al-Nubala' (سير أعلام النبلاء;lit. 'The Lives of Noble Figures') ofAl-Dhahabi (d. 1348), Ibn Lahia's library and the books within, were burned in a fire which occurred in the year 786.^[3]

According to the historian Pavel Pavlovich, Ibn Lahi'a is among "the most disparaged second-[Islamic] century traditionists". The 9th-century historianIbn Sa'd considered him ada'if ('weak') authority, whileal-Juzajani dismissed traditions emanating from him as "unreliable", invalid for use in legal arguments or for transmission. The basis for much of the Islamic scholarly criticism of Ibn Lahi'a is frequent omission of one to three informants in hisisnads (chains of transmission of historical information). The burning of his books in his house fire was dismissed byYahya ibn Ma'in (d. 847) as the justification for Ibn Lahi'a's omissions.^[4]
