The Nizari or more properly the Nizari Isma'ili Muslims, like other Shi'i communities, acknowledge 'Ali as imam after the Prophet. The Nizari Ismailis have continued to give allegiance to imams descended from Imam 'Ali, on the basis of the principle of designation (nass) by the imam of the time. As of 1957, His Highness the Aga Kha, Shah Karim al-Hussaini, is the forty-ninth hereditary imam of the Nizari Ismailis.
