The Rif רב יצחק אלפסי
Author of Sefer HaHalachot — the "little Talmud" that distills the Bavli to its operative law — and the founder of the Sefardic halakhic line: Rif → Ibn Migash → R' Maimon → Rambam. Born near Fez (hence Alfasi), trained by tradition in Kairouan under Rabbeinu Nissim and Rabbeinu Chananel, he fled to Spain at seventy-five and made Lucena the new center of halakha.

V. How do we know
| Claim | Evidence | Confidence | Sources |
|---|---|---|---|
| Abraham ibn Daud's Sefer HaKabbalah (12th c.) records that Alfasi studied in Kairouan under Rabbeinu Nissim and Rabbeinu Chananel — the classical attestation behind both edges; some modern scholars question the Kairouan period, so confidence is tempered. | tradition reconstruction | ★★★☆☆ | |
| His Sefer HaHalachot follows the Talmud's own order while omitting dialectic and non-practical law — the decisive model of codification between the Talmud and the Rambam, and the first of R' Yosef Karo's "three pillars of hora'ah." | rabbinic tradition | ★★★★★ | |
| Denounced to the government in 1088, he fled Morocco to Spain and headed the academy at Lucena, which he passed at his death to his student R' Yosef ibn Migash — over his own son. | external tradition | ★★★★☆ | |
| Born 1013 CE at Qal'at Bani Hammad in the Maghreb; spent his mature career at Fez, from which his epithet derives. | tradition | ★★★☆☆ |
|
| Headed the academy at Lucena until his death in 1103 CE (10 Iyar 4863) and was buried there. | tradition | ★★★☆☆ |
|
| His death was marked by elegies from the Andalusian Hebrew poets, including Yehudah HaLevi and Moshe ibn Ezra.
The elegy exists; the research pass could not verify a poem number in a specific critical edition.
