al-Ismāʿīliyya al-khāliṣa / al-Ismāʿīliyya al-wāqifa[1] or Seveners (Arabic: سبعية) was a branch of Ismā'īlī Shīʻa. They broke off from the more numerous Twelvers after the death of Jafar al-Sadiq in 765 AD. They became known as "Seveners" because they believed that Isma'il ibn Ja'far was the seventh and last Imam (hereditary leader of the Muslim community in the direct line of Ali).[2] They believed his son, Muhammad ibn Isma'il, would return and bring about an age of justice as Mahdi. Their most well-known and active branch were the Qarmatians.

The following Ismaili imams after Mahdi had been considered as heretics of dubious origins by certain Qarmatian groups[3] who refused to acknowledge the imamate of the Fatimids and clung to their belief in the coming of the Mahdi.[4]
