The Muslims are obliged to live in one State, and be ruled by one Khalifah. It is forbidden for the Muslims in the world to have more than one State and more than one Khalifah. .

Haka kuma wajibi ne tsarin mulki a cikin Daular Khilafah ya zama tsarin haɗin kai, kuma haramun ne ya zama tsarin tarayya.

It is also necessary that the ruling system in the Khilafah State be a system of unity, and it is forbidden for it to be a federal system. .

Wannan ya samo asali ne daga abin da Muslim ya ruwaito daga Abdullahi ɗan Amr ɗan al-Aas, wanda ya ce ya ji Manzon Allah ﷺ yana cewa:

This is due to what Muslim narrated on the authority of Abdullah b. Amru b. al- Aas who reported that he heard the Messenger of Allah (P.B.U.H) say: .

"Duk wanda ya yi wa Imam mubaya'a yana ba shi hannunsa da kuma 'ya'yan zuciyarsa, ya kamata ya yi masa biyayya gwargwadon iyawarsa, idan kuma wani ya zo yana jayayya da shi, to dole ne ku sare wuyan wannan na karshen."

"Whoever pledged allegiance to an Imam giving him the clasp of his hand and the fruit of his heart, he should obey him as much as he can, and if another comes to dispute with him, you must strike the neck of the latter". .

An kuma ruwaito daga Muslim cewa Afrajah ya ce: "Na ji Manzon Allah ﷺ yana cewa: ."

It has also been narrated by Muslim that Afrajah said: “I heard the Messenger of Allah (P.B.U.H) say: .

"Duk wanda ya zo muku alhali al'amarinku ya haɗu a kan mutum ɗaya, yana nufin raba ikonku ko warware haɗin kanku, to ku kashe shi." [Muslim, Sahih, #1844].

"Whoever comes to you while your affair has been united over one man, intending to divide your power or dissolve your unity, kill him".” [Muslim, Sahih, #1844] .

Har ila yau, Muslim ya ruwaito daga Abu Sa'id Al-Khudri cewa Manzon Allah ﷺ ya ce:

It has also been reported by Muslim from Abu Said Al Khudri that the Messenger of Allah (P.B.U.H) said: .

"Idan an yi wa Khalifofi biyu mubaya'ar (bai'a), to a kashe na karshe daga cikinsu." [Muslim, Sahih, #1853].

"If the Oath of Allegiance (bayah) has been taken for two Khalifahs, kill the latter of them." [Muslim, Sahih, #1853] .

Muslim ya kuma ruwaito cewa Abu Hazim ya ce, "Na yi tare da Abu Huraira tsawon shekara biyar, na kuma ji yana magana game da maganar Annabi ﷺ cewa:"

Muslim also reported that Abu Hazim said, “I accompanied Abu Huraira for five years and heard him talking about the Prophet’s (P.B.U.H) saying: .

Bani Isra'ila an kasance ana mulki da su ta hannun annabawa; duk lokacin da wani annabi ya rasu, sai wani annabi ya gaje shi; amma babu wani annabi bayana. Za a samu khulafa'u nan ba da jimawa ba, kuma za su yi yawa. Suka ce: To me kake umurce mu da shi?ﷺ

"The children of Israel have been governed by Prophet; whenever a Prophet died another Prophet succeeded him; but there will be no Prophet after me. There will soon be Khulafaa and they will number many; they asked: What then do you order us? .

Ya ce (ﷺ): "Ku cika alkawarin da aka yi musu, ɗaya bayan ɗaya, ku ba su haƙƙinsu; gaskiya Allah zai tambaye su game da abin da ya amince musu da shi."" [Bukhari, Sahih, #3455] ..

He (P.B.U.H) said: Fulfil allegiance to them one after the other, and give them their dues; for verily Allah will ask them about what he entrusted them with".”[Bukhari, Sahih, #3455] ..

Hadithi na farko ya nuna cewa idan an bai wa wani Imamah (Khilafah), to wajibi ne a yi masa biyayya, kuma idan wani mutum ya zo yana kalubalantar ikonsa, to a yaƙe shi a kashe shi idan bai janye kalubalen ba.

The first hadith demonstrates that if the Imamah (Khilafah) has been given to someone he should be obeyed, and if another man comes to dispute his authority, he should be fought and killed if he did not renounce the dispute. .

Hadisi na biyu yana nuna cewa idan Musulmi suna haɗe a karkashin shugabancin Amir guda ɗaya, kuma wani mutum ya zo da niyyar raba ikonsu da warware haɗinkansu, to kashe shi ya zama wajibi. Hadisai biyu a fili suna nuna haramcin tarwatsa Dawla, gargadi mai tsanani game da rarrabata, da hana duk wani yunkuri na ballewa koda kuwa sai an ɗaga takobi (karfi).

The second hadith demonstrates that when the Muslims are united under the leadership of one Amir, and a person comes along with the intent to divide their power and dissolve their unity, his killing becomes compulsory. The two hadiths clearly indicate prohibition of dismembering the State, the strong warning against its division, and preventing any breakaway attempt even if it means raising the sword (force). .

Hadith na uku ya nuna cewa idan babu Khalifa, saboda mutuwa, cirewa ko murabus, sannan aka ba da bai'a ga Khalifofi biyu, to na karshe daga cikinsu ya kamata a kashe shi. Wannan na nufin cewa Khalifa shi ne wanda aka fara ba wa bai'a, yayin da wanda aka ba wa bai'a bayan na farko dole ne a kashe shi idan bai janye kansa daga mukamin Khilafah ba. Idan an karɓi bai'a ga fiye da biyu, to dukkansu, banda mutum na farko da aka ba wa bai'a, dole ne a yaƙe su a kashe su sai dai idan sun janye daga bai'ar. Wannan a fili yake nuna cewa rarraba Dawlah haramun ne, wato mayar da ita ƙananan jihohi haramun ne; dole ne ta kasance Dawla guda ɗaya.

The third hadith indicates that in the case of the absence of a Khalifah, due to death, removal or resignation, and the contracting of the bayah to two Khulafaa, the latter of them should be killed. This means the Khalifah is he who was given the first bayah, whilst the one that who was given the bayah after the first must be killed if he does not withdraw himself from Khilafah post. If the bayah was taken to more than two, then all those, except the first person given the bayah must be fought and killed unless they withdrew from the bayah. This clearly demonstrates that the dismembering of the State is forbidden, which means that turning it into small Statelets is forbidden; it must remain one single State. .

Hadisi na huɗu ya nuna cewa Khulafa'u za su yi yawa bayan Manzon Allah ﷺ, kuma Sahabbai sun tambaye shi abin da ya umarce su su yi idan Khulafa'u sun yi yawa, sai ya amsa cewa su cika mubayi'arsu ga Khulafa'u ɗaya bayan ɗaya, suna farawa da na farko da suka yi wa bai'a, domin shi ne halastaccen Khalifa kuma shi kaɗai ya kamata a yi wa biyayya. Amma game da sauran, ba a yi musu biyayya ba, domin bai'arsu ba ta da inganci, ba ta aiki kuma ba ta halal ba, don an haramta a yi wa wani Khalifa bai'a alhali akwai Khalifa a kan mulki. Wannan hadisi kuma yana nuna cewa wajibi ne a yi biyayya ga Khalifa ɗaya kaɗai. Saboda haka haramun ne ga Musulmi su kasance suna da Khalifa fiye da ɗaya, ko kuma daula fiye da ɗaya.

The fourth hadith indicates that the Khulafaa would number many after the Messenger of Allah (P.B.U.H) and that the Sahabah asked him about what he ordered them to do when the Khulafaa numbered many, and he replied that they should fulfil their allegiance to the Khulafaa one after the other, starting by the first one they gave their bayah to, for he would be the legitimate one and he alone should be obeyed. As for the others, they are not to be obeyed for their bayah is void and null and unlawful, for it is forbidden for another Khalifah to be given a bayah while there exists a Khalifah already in office. This hadith also indicates that obedience to a single Khalifah is obligatory. Therefore it is forbidden for the Muslims to have more than one Khalifah and more than one single State.
