A--- Ushahidi ni mwingi: kuhesabu muda wake kwa miaka thelathini, ambayo ndiyo muda wa uongozi wao, kuwatanguliza kuliko masahaba wengine wote wa Mtume ﷺ, na yale yaliyosimuliwa na Samura bin Jundub, akisema: mtu mmoja alisema: "Ee Mjumbe wa Allah! Niliona kana kwamba ndoo ilishuka kutoka mbinguni. Kisha akaja Abu Bakr akaichukua akanywa kidogo sana kutoka humo. Kisha akaja 'Umar akaichukua akanywa mpaka akashiba. Kisha akaja 'Uthman akaichukua akanywa mpaka akashiba. Kisha akaja 'Ali akaichukua, ikatolewa kutoka kwake na kitu kutoka humo kikanyunyiziwa juu yake." (Abu Dawud na Ahmed)

A--- The proofs are numerous: counting its period with thirty years which is the period of their leadership, preferring them to all other companions of the Prophet (Peace be upon him), and what has been narrated by Samura Ibn Jundub saying: that a man said: “O Allah's Messenger! I saw as if a bucket descended from the sky. Then came Abu Bakr and took it and he drank very few thereof Then, came 'Umar who took it and drank till he got satisfied. Then, came `Uthman who took it and drank till he got satisfied. Then, came `Ali who took it and it was drawn from him and something thereof was spelt over him.” (Abu Dawud and Ahmed)

Zaidi, Umma imekubaliana juu ya Ukhalifa wao, na hakuna anayepinga jambo hili isipokuwa yule aliyepotea na kuchukua bid'a.

In addition, the Ummah has agreed on their Caliphate and none contests against this but who went astray and adopted Innovations.
