- This is a sub-article to Islamic jurisprudence and Twelvers.
Jaʿfarī school of thought, Ja`farite School, Jaʿfarī jurisprudence or Jaʿfarī Fiqh is the school of jurisprudence of most Shi'a Muslims, derived from the name of Jaʿfar as-Ṣādiq, the 6th Shi'a Imam. This school of jurisprudence is followed by Twelvers and Ismailis in general, as well as a small minority of Zaidis.
It differs from the four schools or madhhabs of Sunni jurisprudence in its reliance on ijtihad, as well as on matters of inheritance, religious taxes, commerce, personal status and the allowing of temporary marriage or mutʿa. However, despite these differences, there have been numerous fatwas regarding the acceptance of Jaʿfarī fiqh as an acceptable Muslim madhhab by Sunni religious bodies. These include the Amman Message and a fatwa by Al-Azhar.
