This paper analyzes the relationship between Sufism and Islamic law in eighth/fourteenth century Cairo through the biographical dictionary of Jamal al-Din al-Asnawi (d. 772/1370). Al-Asnawi was born in the town of Esna in Upper Egypt and eventually became the chief of the Shafi’i jurists in Cairo. Al-Asnawi came from a family of scholars, many of whom were Sufis and jurists. Al- Asnawi’s family ties to Sufism and his institutional ties to the Shafi’i legal school make him a compelling window into the relationship between Sufism and Islamic law. Through an analysis of his biographical dictionary, this paper demonstrates the ways in which al-Asnawi integrated Sufis and Sufi thought into the history of the Shafi’i school. In particular, al-Asnawi emphasizes the role of early Sufi masters such as al-Junayd (d. 298/910) and al-Qushayri (d. 468/1074) while underemphasizing other Sufis. Early Sufi masters are, in al-Asnawi’s history, relevant for both their Sufi and legal accomplishments. The role of later Sufis is reduced to legists and their Sufism is either overlooked, i.e. Abu Hafs al-Taliqini (d. 590/1193) and al-Khatib al-Kushmayhani (d. 548/1153-54) or greatly underemphasized, i.e. Hujjat al-Islam al-Ghazali (d. 505/1111) and Ahmad al-Ghazali (d. ca 520/1126). Overall, al-Asnawi’s history gives the impression that the early history of the Shafi’i school is greatly indebted to Sufi masters and that this close connection had gradually faded over time. His portrayal of Sufis in his biographical history is somewhat similar to that of Taj al-Din ibn al-Subki (d. 771/1370), and much more embracing of Sufism than that of Ibn Qadi Shuhba (d. 851/1448), two other prominent Shafi’i historians from the Mamluk era.
