Ya'qub ibn Ibrahim al-Ansari (Arabic: يعقوب بن إبراهيم الأنصاري, romanized: Yaʿqūb ibn Ibrāhīm al-Anṣārī), better known as Abu Yusuf (Arabic: أبو يوسف, romanized: Abū Yūsuf) (729–798) was an Islamic jurist, as well as a student of Abu Hanifa (d.767) and Malik ibn Anas (d.795), who helped spread the influence of the Hanafi school of Islamic law, and was notable for having introduced the Maliki-like position of Urf being a valid source of sunnah, that could overrule literary traditions.
