Isa ibn Aban

Abu Musa ʿĪsā b. Abān was an early Sunni Islamic scholar who followed the Hanafi madhhab. Although none of his own works have survived to today, he was quoted extensively by early Hanafi scholars such as al-Jassas in regards to his views on Hanafi usul al-fiqh. Having studied under Abu Hanifa's student, Muhammad al-Shaybani, ibn Abān's views on the sources of law can be assumed to be representative of Abu Hanifa's.
