Muhammad ibn as-Sā'ib al-Kalbī, also known as Abū n-Nadr, was an Islamic scholar and polymath from Kufa. Born around 737 AD, al-Kalbī is well-regarded for his contributions to Islamic historiography, tafsir (Qur'anic exegesis), and genealogical literature. His works have been foundational to later Islamic traditions and studies.

Muhammad ibn as-Sā'ib al-Kalbī was born and raised in Kufa, Iraq. He received his education there and was known for not traveling extensively, unlike many of his contemporaries.^[1] His scholarly pursuits were profoundly influenced by his upbringing and the rich intellectual environment of Kufa.

Al-Kalbī's most significant contributions lie in his works on tafsir and genealogy. His commentary on the Qur'an, known as "Tafsir al-Kalbī, has been influential in shaping later exegesis.^[2] Additionally, his genealogical works, including those recounting the histories of various Arab tribes, are considered critical sources of historical knowledge.^[3]

Al-Kalbī's historical narratives provide valuable insights into early Islamic history. His accounts of idol veneration in pre-Islamic Arabia are particularly notable.^[4]

Despite his contributions, al-Kalbī's works have not been free from criticism. Some modern scholars debate the authenticity and reliability of his narrations, particularly those attributed to Ibn Abbas.^[5]

Muhammad ibn as-Sā'ib al-Kalbī passed away in 763 AD (146 AH). His legacy, however, endures through his extensive body of work and the influence he continues to wield in Islamic scholarship.^[6] His son, Hisham ibn al-Kalbi, also followed in his footsteps, becoming a renowned scholar and narrator.
