Education and Teachers

In Kufa, al-Shaybani joined the teaching circle of Abu Hanifa for approximately two years until the master's death, when al-Shaybani was around eighteen years old Wafayat al-Ayan+1. He then completed his legal training under Abu Hanifa's senior disciple, Abu Yusuf Wafayat al-Ayan+1.

He traveled to Medina and studied under Malik ibn Anas for over three years, transmitting more than seven hundred hadiths directly from his speech Majallat al-Buhuth al-Isl…+1. His other prominent teachers in hadith and law included Sufyan al-Thawri, al-Awza'i, Mis'ar ibn Kidam, Malik ibn Mighwal, and Umar ibn Dharr al-Madkhal ila Dirasat al…+1.

Career and Students

Al-Shaybani established himself in Baghdad, where he conducted legal and hadith circles at the Sham Gate (Bab al-Sham) al-Madkhal ila Dirasat al…+1.

His extensive writings, including al-Asl (also known as al-Mabsut) and al-Jami al-Saghir, served as foundational references for substantive legal rulings across multiple legal traditions Wafayat al-Ayan+1.

Al-Shafi'i held him in high esteem, remarking that he took a camel-load of books from his knowledge and praising his eloquence by noting that listening to his speech gave the impression that the Quran had been revealed in his dialect al-Nawadir - Mualla ibn M…+1.

His death coincided with that of the prominent Kufan grammarian and reader al-Kisa'i, who died in Rayy on the same day or within two days, prompting Harun al-Rashid to lament: "Jurisprudence and the Arabic language have been buried in Rayy" Taj al-Tarajim fi Tabaqat…+1.
