Uhalisia huu wa msaidizi au Waziri katika maana ya Shari'ah ni tofauti kabisa na uhalisia wa wizara katika mfumo wa kidemokrasia. Hii ni kwa sababu wizara katika mfumo wa kidemokrasia ni serikali, ambayo ni kundi la watu ambao, kwa nafasi yao kama kundi maalum, wanatekeleza utawala. Hii ni kwa sababu utawala, kwa mtazamo wao, ni wa kundi na si wa mtu binafsi. Kwa maneno mengine, Imarah ni ya pamoja na si ya mtu mmoja.
Hivyo, mtawala halisi mwenye mamlaka yote ya lazima ya kutawala ni serikali, yaani kundi la mawaziri, na hakuna hata mmoja wao anayemiliki mamlaka kamili ya kutawala, bali mamlaka hayo yamegawanywa kati ya baraza zima la mawaziri. Kwa upande wa waziri mmoja mmoja, amepewa eneo moja la utawala ambalo ndani yake atakuwa na mamlaka ya lazima, ambayo serikali kwa ujumla inamkabidhi. Maeneo yasiyokabidhiwa kwake yanabaki mikononi mwa serikali kama baraza, si kwake yeye binafsi. Kwa mfano, waziri wa sheria ana mamlaka fulani ya lazima ndani ya wizara yake, lakini kuna mambo mengine ambayo hana mamlaka nayo, bali yanaamuliwa na kuendeshwa na serikali nzima. Hii ndiyo hali halisi ya serikali katika mfumo wa kidemokrasia.
Kutokana na hilo, tunaona tofauti kubwa kati yake na Wizara ya mfumo wa Kiislamu, na pia tunaona tofauti kubwa ya maana kati ya neno Wazir, yaani msaidizi katika Uislamu, na neno Wazir, yaani waziri katika mfumo wa kidemokrasia. Kwa hiyo, Wazir na Wizara (waziri na wizara) katika mfumo wa Kiislamu maana yake ni msaidizi wa Khalifah katika majukumu yake yote bila ubaguzi, ambapo anatekeleza majukumu hayo na kumripoti Khalifah. Wizara ni nafasi ya mtu mmoja anayeiendesha, na kama ingepewa zaidi ya mtu mmoja, kila mmoja wao angekuwa na mamlaka ya lazima sawa na aliyonayo Khalifah. Wizara katika mfumo wa kidemokrasia, kwa upande mwingine, kwa kweli ni kundi, si mtu mmoja, ambapo kila waziri ana mamlaka juu ya eneo maalum la utawala pekee. Yeye hana mamlaka kamili bali mamlaka yaliyo na mipaka. Yaliyotajwa hapo juu yanaonyesha wazi tofauti kati ya dhana ya Wazir na Wizara katika Uislamu na dhana zao katika mfumo wa kidemokrasia.
Hata hivyo, maana ya Wazir na Wizara kama inavyoonyeshwa na mfumo wa kidemokrasia ndiyo maana inayotawala na iliyoenea; na inapotajwa, ndiyo maana inayowajia watu akilini papo hapo. Kwa hiyo, ili kuondoa mkanganyiko wowote na kubainisha maana halisi ya Shari'ah kwa kuwaondoa maana nyingine zote, haifai kuwaita wasaidizi wa Khalifah Wazir na kutumia neno Wizara bila kizuizi. Badala yake, anapaswa kuitwa msaidizi (Mu'awin), na hiyo ndiyo maana halisi. Kwa upande mwingine, inapaswa kuwekwa aina fulani ya kizuizi wakati wa kutumia maneno Wazir na Wizara ili kuondoa maana ya kidemokrasia na kuonyesha maana ya Kiislamu pekee.
Kutokana na haya yote tunapata kwamba Mu'awin ni mtu ambaye ukabidhi wake unajumuisha kazi zote za dola katika maeneo yote ya dola. Kwa hiyo, inasemwa: "Khalifah humkabidhi msaidizi ukabidhi wa jumla kama naibu wake mwenyewe." Hivyo, hali halisi ya kazi ya Mu'awin ni kuwa naibu wa Khalifah; unaibu huu unapaswa kuwa wa jumla, ukijumuisha mambo yote ya dola, yaani, yeye ni mtawala msaidizi.
This reality of the assistant or the Wazir in Shari’ah terms is totally different to the reality of the ministry in the democratic system. This is because the ministry in the democratic system is the government; which is a group of individuals who, in their capacity as a particular group, carry out the ruling. This is because ruling, in their view, belongs to the group not to the individual. In other words, the Imarah is collective and not singular. Thus, the actual ruler who enjoys all the mandatory powers to rule is the government i.e. a group of ministers as a minister and none of them enjoys the absolute mandate to rule, but the mandate to rule is shared amongst the whole cabinet. As for the single minister, He is assigned to one area of ruling in which He would posses mandatory powers, which the government as a whole assigns to him. As for the areas not been assigned to him, they remain in the hands of the government as a cabinet and not to Him in person. For instance, the minister of justice enjoys some mandatory powers within his ministry and there are other matters over which He has no mandate, rather they are decided and run by the government as a whole. This is the reality of the government in the democratic system. From it we notice a marked difference between it and the Wizara of the Islamic system and we can also see a wide difference in meaning between the word Wazir i.e. assistant in Islam and the word Wazir i.e., minister in the democratic system. Therefore, the Wazir and the Wizara (minister and ministry) in the Islamic system means the Khaleefah’s assistant in all his duties without exception, wherein He performs such duties and reports back to the Khaleefah. The wizara is a singular position run by one person, and if it were given to more than one person each one of them would enjoy the same mandatory powers that the Khaleefah possesses. The Wizara (ministry) in the democratic system, on the other hand, is in fact a group, and not an individual, where each minister has powers only over a specific area of ruling. He does not enjoy full powers rather limited ones. The above clearly illustrates the difference between the concepts of the Wazir and the Wizara in Islam and their concepts in the democratic system. Nevertheless, the meanings of the Wazir and the Wizara as portrayed by the democratic system are the meanings that are predominant and widespread; and once mentioned, they are the meanings that immediately spring to people’s minds. Therefore, to remove any confusion and to determine the exact Shari’ah meaning to the exclusion of all other meanings, it would be invalid to call the Khaleefah’s assistants Wazirs and use the term Wizara without restriction. Rather, He should be called assistant (Mu’awin) and that would be the true meaning. On the other hand, some form of restriction should be laid down when using the words Wazir and Wizara to dismiss the democratic meaning and indicate the Islamic meaning alone.We gather from all this that the Mu’awin is the person whose delegation includes the whole of the state’s functions in the whole of the state’s territories. Therefore, it is said; “the Khaleefah delegates to the assistant a general delegation as a deputy to himself.” Thus, the reality of the Mu’awin’s job is that it is a deputyship for the Khaleefah; this deputyship should be general, including all the affairs of the state, i.e. He is an assistant ruler.
