Mu’āwin-ut-Tanfīdh — bu Xalifa tomonidan o‘zining ishini bajarish, kuzatish va buyruqlarini amalga oshirishda yordamchi qilib tayinlaydigan Vazir. U Xalifa bilan davlatning turli idoralari, aholi va boshqa tomondan tashqi ishlar idorasi o‘rtasidagi vositachidir. U bir tomondan Xalifadan xabarlarni yetkazadi, boshqa tomondan esa unga xabarlarni yetkazadi. Shu sababli u buyruqlarni bajarishda yordamchidir, odamlar ustidan hukmdor emas va ularni uning ixtiyoriga berilmagan. Demak, uning vazifasi ma’muriy bo‘lib, hukmronlik emas, uning idorasi esa Xalifa ichki va tashqi idoralarga bergan buyruqlarni bajarish vositasi hamda bu idoralardan unga kelgan barcha narsalarni unga topshirish vositasidir. Uning idorasi Xalifa bilan boshqalar o‘rtasida vositachi bo‘lib xizmat qiladi: uning nomidan ularga yetkazadi va ulardan unga yetkazadi.

Mu’awin-un-Tanfeedh is the Wazir whom the Khaleefah appoints to be his assistant in the execution and follow up and performance of his orders. He is the intermediary between the Khaleefah and the state’s various departments, the subjects and the foreign office on the other side. He conveys messages, on the one hand, from the Khaleefah and on the other hand to him. As a result, He is an assistant in executing orders and not a ruler over people, nor is He entrusted with them. His work is therefore administrative and not ruling, and his department is a tool used to execute what the Khaleefah issues to the domestic and foreign offices, and to submit to Him all that comes to Him from these offices. His department acts as an intermediary between the Khaleefah and others, where it conveys to them on his behalf and conveys to Him from them.
