When Shara made it incumbent upon the Ummah to appoint a Khalifah, it determined for her the method by which the Khalifah is appointed. This method is proven in the Book and the Sunnah. The Muslims who must give the bayah are those that are citizens of the Khilafah at that time. In the case where there is no Khilafah the Muslims responsible for giving the bayah are those living in the region where the Khilafah should be implemented. .

Hanyar zaɓen Khalifah ta hanyar bai'ah an tabbatar da ita daga misalin bai'ah da Musulmai suka yi wa Annabi (ﷺ), da kuma umarnin Manzon Allah (ﷺ) gare mu, na mu yi wa Imam bai'ah. Bai'ar Musulmai ga Manzon Allah (ﷺ) ba bai'ah ce a kan annabci ba, a'a bai'ah ce a kan mulki, domin ta kasance game da aiki ba game da imani ba. Saboda haka, an yi wa Manzon Allah (ﷺ) bai'ah a matsayin shugaba mai mulki, ba a matsayin Annabi ko Manzo ba (ﷺ). Wannan saboda amincewa da annabci da manzanci yana da alaƙa da imani, ba da bai'ah ba. Don haka bai'ar da aka yi masa (ﷺ) ta kasance ne kawai bisa matsayinsa na shugaban ƙasa.

The method of electing the Khalifah through a bayah is proved from the example of the Bayah given by the Muslims to the Prophet (P.B.U.H), and from the order of the Messenger (P.B.U.H) to us, to pledge Bay’ah to the Imam. The Bayah of the Muslims to the Messenger (P.B.U.H) was not a Bayah on Prophethood, but a Bayah over ruling, for it was regarding action not belief. Therefore, Rasool Allah (P.B.U.H) was pledged allegiance to as a ruler, and not as a Prophet or a Messenger (P.B.U.H). This is because acknowledging the Prophethood and Messengership is linked to belief (Iman), and not a Bayah. Hence the Bayah to Him (P.B.U.H) was only in his capacity as the head of the state. .

Ana kuma ambaton Bai'a a cikin Alkur'ani da Hadisi. Allah (SWT) yana cewa:

The Bayah is also mentioned in the Qur’an and Hadith. Allah (S.W.T) says:.

Ya kai Annabi! Idan muminai suka zo wurinka domin su yi mubaya'a (Bay'ah) cewa ba za su yi shirki da Allah da wani abu ba, ba za su yi sata ba, ba za su yi zina ba, ba za su kashe 'ya'yansu ba, ba za su yi kage ba, suna ƙirƙirar ƙarya da gangan, kuma ba za su saɓa maka ba a cikin wani al'amari na gaskiya (Ma'roof), to ka karɓi mubaya'arsu (Bay'ah).ﷺ [TMQ: 60:12] A wata aya kuma Allah (S.W.T) yana cewa: .

"O Prophet! If the believers come to you to take the oath (Bay’ah) that they will not associate [in worship] anything with Allah, that they will not steal, that they will not commit adultery, that they will not kill their children, that they will not utter slander, intentionally forging falsehood, and they will not disobey you in any just matter (Ma’roof), then receive their oath (Bayah)." [TMQ: 60:12] In another verse Allah (S.W.T) says: .

Lalle waɗanda suke yi maka mubaya'a, ba komai suke yi ba face suna yi wa Allah mubaya'a. Hannun Allah yana bisa hannayensu." [TMQ: 48:10].

Verily those who pledge their allegiance to you do no less than pledge their allegiance to Allah: The Hand of Allah is over their hands." [TMQ: 48:10].

Al-Bukhari ya ruwaito daga Isma'il, wanda ya ruwaito daga Malik, wanda ya ruwaito daga Yahya bin Sa'id, wanda ya ce: "Ubadah bin Al-walid ya gaya mini cewa mahaifina ya gaya mini cewa Ubadah bin al-Samit ya ce:

Al-Bukhari narrated on the authority of Isma’il, who reported on the authority of Malik, who reported on the authority of Yahya bin Sa‘id who said: “Ubadah bin Al-walid told me, that my father told me that Ubadah bin al-Samit said: .

"Mun yi wa Manzon Allah ﷺ mubaya'a cewa za mu saurara mu yi biyayya cikin sauki da kuma cikin wahala, kuma cewa ba za mu yi jayayya a kan al'amarin (iko) da mutanensa ba, kuma cewa za mu tsaya mu faɗi gaskiya duk inda muke, kuma cewa a cikin hidimar Allah ba za mu ji tsoron zargin kowa ba." [Bukhari, Sahih, #7054 da Muslim, Sahih, #4748].

"We have pledged allegiance to the Messenger of Allah to listen and obey in ease and in hardship and that we do not dispute the matter (authority) with its people and that we stand for and speak the truth wherever we are and that in the service of Allah we would fear the blame of no one.” [Bukhari, Sahih, #7054 and Muslim, Sahih, #4748] .

Muslim ya ruwaito cewa Abdullah ɗan Amr ɗan al-As ya ce: Manzon Allah ﷺ ya ce:

Muslim has reported that Abdullah ibn Amru ibn al-As narrated that the Messenger of Allah (P.B.U.H) said: .

"Duk wanda ya yi mubaya'a ga Imam ta hanyar ba shi hannunsa da kuma zuciyarsa, to ya bi shi muddin yana iya, amma idan wani ya zo yana jayayya da shi, to ku kashe wannan na karshen." [Ahmad, Musnad, 3/10] ..

"Whosoever pledges allegiance to an Imam by giving him the clasp of his hand, let him obey him if he is able to do so, but if another comes along to dispute with him, then kill the latter." [Ahmad, Musnad, 3/10] ..

A cikin Muslim an ruwaito cewa Abu Sa'eed Al-Khudri ya ruwaito cewa Manzon Allah ﷺ ya ce:

Also in Muslim it is narrated that Abu Saeed Al-Khudri reported that the Messenger of Allah (P.B.U.H) said: .

"Idan an yi wa khulafa'u biyu mubaya'a, to ku kashe na karshe daga cikinsu." [Muslim, Sahih, #1853] ..

“If two Khulafaa’ were pledged allegiance, then kill the latter of them." [Muslim, Sahih, #1853] ..

Muslim ya ruwaito daga Abi Hazim, wanda ya ce: "Na yi tare da Abu Huraira shekara biyar, na ji shi yana ba da labarin maganar Annabi ﷺ: 'Banu Isra'ila a kan a yi musu mulki ta hannun annabawa; duk lokacin da wani annabi ya mutu, sai wani ya zo bayansa, amma babu annabi bayan ni. Za a sami halifofi, kuma za su yi yawa.' Suka ce: 'To me kake umurtar mu mu yi?' Ya ce ﷺ: 'Ku cika wa'adin biyayya gare su, ɗaya bayan ɗaya, ku ba su haƙƙinsu. Lalle Allah zai tambaye su game da abin da ya danƙa musu.'" [Bukhari, Sahih, #3455].

Muslim narrated on the authority of Abi Hazim who said: “I accompanied Abu Huraira for five years and I heard him talk of the Prophet’s (P.B.U.H) saying: "Banu Israel used to be governed by Prophet, every time a Prophet died, another came after him, and there is not Prophet after me. There will be Khulafa’ and they will number many". They said: "What would you order us to do?" He (P.B.U.H said: "Fulfil the Bayah to them one after the other, and give them their due right, surely Allah will account them for that which He entrusted them with".” [Bukhari, Sahih, #3455] .

Waɗannan nassosin daga Littafi da Sunnah sun bayyana a fili cewa hanyar naɗin Khalifah ita ce Bai'ah. Wannan ne Sahabbai duka suka fahimta kuma suka aikata. Bai'ar da aka yi wa Khulafa'u Rashidun ta bayyana wannan a sarari.

These texts from the Book and the Sunnah explicitly state that the method of appointing a Khalifah is by the Bayah. This was understood and practiced by all of the Sahabah. The bayah given to the rightly guided Khulafaa’ was clear in this regard. .
