Scholarly Reception and Lasting Influence

Ath-Tha'labi's Al-Kashf wal-Bayan was widely read and cited in the eastern Islamic world during the fifth and sixth Islamic centuries, and its influence on subsequent tafsir literature was significant. Several major later works drew directly on it, sometimes acknowledging the debt and sometimes not.

Abu al-Hasan al-Wahidi (d. 468 AH), ath-Tha'labi's most distinguished student, produced two works in Quranic exegesis — Al-Basit and Al-Wajiz — that drew on his teacher's tafsir extensively. Al-Wahidi was more rigorous in his hadith critical evaluation than ath-Tha'labi, and his works represent something of a refinement of the Khurasani tafsir tradition that his teacher had established.

The Persian scholar al-Husayn ibn Masud al-Baghawi (d. 516 AH) produced his influential Tafsir al-Baghawi (Ma'alim at-Tanzil) as an abridgment and partial revision of ath-Tha'labi's work. Al-Baghawi explicitly removed many of the weak and fabricated hadith that ath-Tha'labi had included, making the text more reliable while reducing its documentary scope. The relationship between the two works illustrates the ongoing process of refinement within the tafsir tradition.

Western Islamic scholars also encountered Al-Kashf wal-Bayan through manuscript copies that circulated across the Muslim world. Its narrative richness made it attractive to audiences beyond the scholarly class, and sections dealing with the stories of the prophets appear to have circulated independently in some manuscript traditions.

Modern critical editions of Al-Kashf wal-Bayan, produced largely from the late twentieth century onward, have made the text accessible to contemporary scholars. Academic researchers in Islamic studies have drawn on it extensively for studies of early exegesis, the Isra'iliyyat tradition, and the literary culture of Khurasani Islamic scholarship in the fourth and fifth Islamic centuries. The multi-volume critical edition produced by Dar Ihya al-Turath al-Arabi has made the work fully accessible to modern scholars and has stimulated renewed interest in ath-Tha'labi's contributions to the tafsir tradition — contributions that were long partially obscured by the greater circulation of al-Baghawi's abridgment, which drew on his work without always making the debt explicit.
