Ḥanafī
Abu Hanifa's pupils Abu Yusuf and Muhammad al-Shaybani transmitted the teachings that formed the early Ḥanafī school. Under the Abbasids, Abu Yusuf became chief judge during the reign of Harun al-Rashid, who ruled from 786 to 809.
The Ottoman Empire adopted Hanafi law as its official school. In seventeenth-century Mughal India, the compilation known as the Fatawa Alamgiri served as a legal reference under Emperor Aurangzeb and continued to be used in South Asia in the eighteenth century.
