A madhhab (Arabic مذهب [mæðhæb] pl. مذاهب [mæðæːhıb]) is an Islamic school of law, or fiqh (religious jurisprudence). There are eight madhhabs in Sunni Islam: Maliki, Hanafi, Hanbali, Shafi'i, Zahiri, Jariri, Thawri, Awzai, and Laysi.
There are also non-denominational Muslims, who are not affiliated with any of those schools: other Sunnis, as well as Shias and Ibadis.
This is due to the historical, sociological, cultural, rational and non-denominational (non-madhhabi) approaches to Islam employed at IAINs, STAINs, and UINs, as opposed to the theological, normative and denominational approaches that were common in Islamic educational institutions in the past
