This intransigent declaration of 'Ali forms the most important and the earliest theoretical point which ultimately gave rise to the later development of two different schools of law under the titles of Shi'i and Sunni, the former including the Ithna 'Ashari, Isma'ili, and Zaydi, the latter including the Hanafi, Maliki, Shafi'i and Hanbali. If ideological differences between the two schools date back to the event of the Saqifa, the differences, in legal matters at least theoretically, must be dated from 'Ali's refusal to follow the precedents of the first two caliphs.
Kwa upande mwengine sifa za Imamu Ali (a.s) na utukufu wake unashuhudiwa na kila mmoja wetu, Imamu Ali (a.s) tangu alipozaliwa hadi kufa kwake alikuwa ndiye Muumini bora aliyetii amri za Mola wake na Mtume wake Muhamaad (s.a.w.w), na aliiendesha serikali ya dini katika mfumo ule ule aliouacha Mtume Muhammad (s.a.w.w.), na kwa sababu ya utukufu wake mtu huyo Mwenyeezi Mungu Mtukufu alimchagua kuwa ni khalifa na kiongozi wa kuiongoza dini yake baada ya Mtume Muhammad (s.a.w.w).
