The Nizaris regard Hassan bin (son of) Ali as a Trustee Imam (imam al-mustawda) as opposed to a Hereditary Imam (imam al-mustaqarr). This fact is clearly demonstrated in the recitation of the Nizari Ismailis’ daily prayers three times a day in which although Hassan bin Ali is revered as part of the Prophet's personal family (Ahl al-Bayt), his name is not included in the hereditary lineage from their first Imam, Imam Ali, to their 49th Imam Prince Karim al Hussaini. If Hassan bin Ali's name were to be included as one of the Ismaili Imams in their prayer recitation then the present Imam Prince Karim of the Nizari Ismailis would have to be the 50th Imam and not the 49th Imam - the way he has identified himself and is known to the world.
