Al-Qassab

Al-Qassab, born Abu Ahmad Muhammad ibn Ali ibn Muhammad al-Karaji, was a Muslim scholar of the Zahiri school of Islamic jurisprudence who died in 970 CE in Karaj in central Iran. Before his scholarly career he served as a soldier under the Abbasid Caliphate, earning the nickname Qassab, meaning butcher, for his skill in battle. He wrote a commentary on the Quran centered on its applications in Islamic law, argued through linguistic analysis, and he held distinctive legal positions, including that the testimony of a convicted criminal could be accepted in unrelated cases after public repentance; his work influenced later scholars such as Ibn Hazm.
