Abu al-Layth as-Samarqandi

Nasr ibn Muhammad ibn Ahmad Abu al-Layth as-Samarqandi (c. 286-373 AH / c. 898-983 CE) was a major Hanafi jurist, Quran commentator, and ethical writer from Samarqand (modern Uzbekistan). Known by the honorific Imam al-Huda (Leader of Guidance) for his piety and scholarship, he studied under the leading Hanafi scholars of Transoxiana and became one of the foremost authorities in the region.

Abu al-Layth's works cover multiple disciplines of Islamic learning. His Tanbih al-Ghafilin (Warning the Heedless) is one of the most widely read works of Islamic ethics and religious exhortation in history — a collection of stories, hadiths, and moral reflections aimed at awakening spiritual consciousness and encouraging repentance and good deeds. This work was translated into numerous languages and read across the Muslim world for centuries.

His Bahr al-Ulum (The Sea of Knowledge) is a tafsir of the Quran that draws on earlier exegetes and provides accessible explanations of the meanings of Quranic verses. He also authored Fatawa an-Nawazil, a collection of legal opinions (fatawa) on novel cases (nawazil), which is an important early source in Hanafi jurisprudence on practical legal questions. His works reveal a scholar deeply concerned with the practical religious and ethical guidance of ordinary Muslims.

Abu al-Layth as-Samarqandi passed away in Samarqand in approximately 373 AH. His Tanbih al-Ghafilin continues to be published and read across the Muslim world as one of the most accessible and enduring works of classical Islamic spiritual and ethical literature.
