Shunday qilib, Payg‘ambar ﷺ zamonida Payg‘ambar ﷺning ikki yordamchisi bo‘lgan Abu Bakr va ‘Umar (roziyallohu anhuma) muayyan vazifalarni bajarish bilan umumiy nazorat qilish vazifasi yuklangan edi. Ular ikki vazir bo‘lib, umumiy nazorat va o‘rinbosarlik vazifasi bilan tayinlangan edilar, bu esa o‘rinbosarlik vazirligi talab qiladigan tartibdir. ‘Umar zamonida ‘Ali va ‘Usmon ham xuddi shunday holatda edilar. Hatto Abu Bakr zamonida ham ‘Umarning Abu Bakrga ko‘rsatgan yordami umumiy nazorat va o‘rinbosarlikda aniq namoyon bo‘lardi, shu darajaga yetganki, ba’zi sahobalar Abu Bakrga: “Biz xalifa kim ekanini bilmaymiz: ‘Umarmi yoki sizmi?” deyishgan. Shunga qaramay, Abu Bakr ba’zi davrlarda ‘Umarni qozilik lavozimiga tayinlagan, buni al-Bayhaqiy rivoyat qilgan va al-Hofiz [Ibn Hajar al-‘Asqalaniy] bu rivoyatni tasdiqlagan.
Demak, Payg‘ambar ﷺning siyrati va undan keyingi Rashidun xalifalarining amaliyotidan shu narsa tushuniladiki, yordamchiga umumiy nazorat va o‘rinbosarlik ishonib topshiriladi. Shu bilan birga, yordamchini muayyan joy yoki vazifaga tayinlash ham joiz, xuddi Payg‘ambar ﷺ Abu Bakr va ‘Umar bilan, Abu Bakr esa ‘Umar bilan qilganidek. Masalan, bir yordamchini Xalifalik davlatining shimoliy hududlarini kuzatishga, boshqasini janubiy hududlarini kuzatishga tayinlash mumkin. Xalifa birinchi yordamchini ikkinchi o‘ringa, ikkinchisini birinchi o‘ringa qo‘yishi ham mumkin. U bir yordamchini muayyan vazifaga, boshqasini boshqa vazifaga yo‘naltirishi mumkin, Xalifaga yordam berish uchun qanday zarur deb bilsa, shunday qila oladi. Bunday hollarda yordamchiga yangi tayinlov kerak bo‘lmaydi; uni faqat bir vazifadan boshqasiga o‘tkazish kifoya. Chunki unga asosan umumiy nazorat va o‘rinbosarlik ishonib topshirilgan, bu vazifalarning barchasi uning yordamchilik lavozimi doirasiga kiradi. Bu jihatdan muovin (yordamchi) hokimdan (vali) farq qiladi: hokim bir joyda umumiy nazorat bilan topshirilgan bo'lib, boshqa joyga ko'chirilmaydi. Agar uni ko'chirishsa, yangi joy birinchi topshiriqqa kiritilmagani uchun unga yangi tayinlash kerak bo'ladi. Biroq muovin umumiy nazorat va o'rinbosarlik bilan topshirilgan, shuning uchun u asosan barcha vazifalarda umumiy nazorat va o'rinbosarlik bilan topshirilgan bo'lgani sababli, yangi o'rinbosarlik talab qilinmasdan bir joydan boshqa joyga ko'chirilishi mumkin.
This means Abu Bakr and ‘Umar (ra), the two assistants of the Messenger of Allah (PBUH), were charged with general examination in specific tasks at the time of the Messenger of Allah (PBUH), though they were two assistants (wazirs) that were appointed with general examination and deputyship, as is required by the ministry of deputyship. This was the case of ’Ali and ‘Uthman at the time of ‘Umar. Even at the time of Abu Bakr, the assistance of ‘Umar to Abu Bakr was evident in the general examination and deputyship, to the point that some of the Sahabah said to Abu Bakr, “We do not know who the Khalifah is? Is it ‘Umar or you?’ Yet, Abu Bakr appointed ‘Umar in a post of judiciary in some periods, as it is reported by al-Bayhaqi through a narration which was corroborated by al-Hafiz [Ibn Hajar al- ‘Asqalani]. Thereupon, it is understood from the Seerah of the Messenger (PBUH) and the khulafa’ Rashidun after him that the assistant is entrusted with the general examination and deputyship. However, it is allowed that the assistant is designated to a specific place or task, as the Prophet (PBUH) did with Abu Bakr and ‘Umar, and as Abu Bakr did with ‘Umar. This is like appointing an assistant to follow up the northern regions whilst appointing another to follow up the southern regions of the Khilafah state. The Khalifah is allowed also to put the first assistant in the position of the second and the second in the position of the first. He can direct one assistant to a specific task, and another to a different task, anyway he deems fit to help the Khalifah. In such cases an assistant does not require a new designation; he needs only to be transferred from one task to another. This is because he is entrusted originally with the general examination and deputyship, and all of these tasks are within his appointment as an assistant. The assistant differs in this regard from the governor (wali), where the governor is entrusted with the general examination in one place without being transferred from it. In case he is transferred he would rather need new appointment, because the new place is not included in the first appointment. However, the assistant is entrusted with the general examination and deputyship, so he is allowed to be transferred from one place to another without the need of new deputyship, since he is in origin entrusted with the general examination and deputyship in all the tasks. .
