Abu Abd Allah al-Sharif al-Tilimsani (710–771 AH / 1310–1370 CE) was an Algerian Maliki jurist, legal theorist, and theologian from Tlemcen, regarded as the preeminent Maliki authority of his era in the Maghrib and best known for his work on legal theory, Miftah al-wusul ila bina al-furu ala al-usul (The Key to Attainment in Grounding Substantive Law on Legal Theory).
Lineage and Early Life
His full name was Muhammad ibn Ahmad ibn Ali al-Idrisi al-Hasani, known as al-Alwayni and al-Sharif al-Tilimsani. He traced his descent to the Prophet's grandson al-Hasan ibn Ali through the Idrisid line. He was born in 710 AH (1310 CE)—though another report gives his birth year as 716 AH—in the village of al-Alwayyin in the district of Tlemcen, where he grew up. During his childhood, he studied the Quran under Ibn Ya'qub, and his maternal uncle Abd al-Karim took him along to attend scholarly circles at an early age.
Education and Scholarly Travels
In Tlemcen, he studied jurisprudence, legal theory, and scholastic theology under the two sons of al-Imam (Abu Zayd and Abu Musa). He then closely studied under Abu Abd Allah al-Abili, from whom he acquired both rational and mathematical disciplines, including logic, philosophy, geometry, astronomy, arithmetic, and inheritance law. Among his other teachers were al-Qadi al-Tamimi, Imran al-Mashdhali, Ibn Zaytun, and al-Satti.
In 740 AH, he traveled to Tunis, where he met Ibn Abd al-Salam al-Tunisi. The two held scholarly debates and studied reciprocally; Ibn Abd al-Salam acknowledged his intellectual standing and read texts with him on philosophy, logic, Sufism, geometry, and astronomy, while al-Sharif al-Tilimsani also benefited from Ibn Abd al-Salam's scholarship.
Career and Political Life
Following his return to Tlemcen, al-Sharif al-Tilimsani took up teaching. When the Marinid sultan Abu Inan Faris seized Tlemcen around 753 AH after the death of his father, he took al-Sharif al-Tilimsani with him to Fez. Relations with the sultan soured, leading to his imprisonment for a month. Abu Inan released him in 756 AH and distanced him, before restoring him to favor in 759 AH.
After the Zayyanid ruler Abu Hammu Musa II took control of Tlemcen, he invited al-Sharif al-Tilimsani to return. Abu Hammu married his daughter to him and built a madrasa in Tlemcen specifically for him, where he taught for the remainder of his life.
Standing and Students
Scholars across the Maghrib acknowledged al-Sharif al-Tilimsani as the foremost scholar of his time, with his contemporary Ibn Marzuq the Elder affirming that he reached the rank of independent legal reasoning (ijtihad). Ibn Khaldun praised him as an unchallenged master of both rational and traditional sciences (faris al-ma'qul wa-l-manqul). Lisan al-Din ibn al-Khatib routinely sent his new writings to him for review and critique.
His prominent students included his two sons, Abu Muhammad Abd Allah and Abu Yahya Abd al-Rahman, as well as Ibn Khaldun, Abu Ishaq al-Shatibi, Ibn Zamrak, and Ibn Abbad al-Rundi. In addition to his celebrated work Miftah al-wusul, he authored a treatise on logical fallacies titled Matharat al-ghalat fi al-adilla (Sources of Error in Proofs), as well as Sharh Jumal al-Khunaji, a commentary on logic.
Death
Al-Sharif al-Tilimsani died in Tlemcen in Dhu al-Hijja 771 AH (1370 CE). A dedicated biographical treatise on his life was later abridged under the title al-Qawl al-munif fi tarjamat al-imam Abi Abd Allah al-Sharif.

List of Works
Matharat al-Ghalat fi al-Adilla (Sources of Error in Proofs) is a concise treatise on logical fallacies, semantic errors, and argumentation in rational and legal reasoning. Written in response to an inquiry requesting a technical classification of errors in demonstration and disputation, the work methodically categorizes verbal and conceptual pitfalls, illustrating them with examples drawn from rational theology and Islamic jurisprudence.
Miftah al-Wusul ila Bina al-Furu ala al-Usul (The Key to Attainment in Grounding Branches on Principles) is a treatise on legal theory (usul al-fiqh) belonging to the genre of takhrij al-furu ala al-usul. The work focuses on deriving substantive legal rulings directly from theoretical maxims and principles, comparing and applying these rules across the Maliki, Hanafi, and Shafi'i legal schools.
