Zayd ibn Ali
Zaydis, also known as Fivers, follow the Zayidi school of thought (named after Zayd ibn Ali). Isma'ilism is another offshoot of Shia Islam that later split into Nizari Ismaili and Musta’li Ismaili, and then Mustaali was divided into Hafizi and Taiyabi Ismailis. Tayyibi Ismailis, also known as "Bohras", are split between Da'udi Bohras, Sulaymani Bohras, and Alavi Bohras.
