Sera ya usimamizi wa maslahi inategemea unyenyekevu wa mfumo, kasi katika kushughulikia kazi, na umahiri wa wasimamizi. Hii inatokana na asili ya kushughulikia maslahi, kwani mtu anayehitaji huduma anahitaji kuipata haraka na kushughulikiwa kwa ufanisi. Mtume wa Allah ﷺ alisema: "Hakika Allah ameamuru ukamilifu katika kila kitu; kwa hiyo mkiua, uueni kwa njia nzuri, na mkichinja, chinjeni kwa njia nzuri" Imepokewa na Muslim kutoka kwa Shaddad bin Aws [Sahih, #1955]. Kwa hiyo, ukamilifu katika kutekeleza vitendo umeamriwa na Sharia. Ili kufikia hili, usimamizi unapaswa kuzingatia sifa tatu.

The policy of administration of the interests is based on the simplicity of the system, speed in processing the tasks and the competence of the administrators. This is taken from the nature of processing the interest, for the person who requires a service needs to have it quickly and efficiently processed. The Messenger of Allah (PBUH) said: "Verily Allah has enjoined the perfection to everything; so when you kill, do so in a good way and when you slaughter, slaughter in a good way" narrated by Muslim from Shaddad b. Aws [Sahih, #1955].. Therefore, the perfection in executing the actions is ordered by the Sharia. To achieve this, the administration should observe three qualities. .

Kwanza, urahisi wa mfumo ambao ungeleta urahisi wa utekelezaji, ilhali ugumu ungeleta mashaka.

o Firstly, the simplicity of the system which would lead to the ease of processing, whereas complication would lead to hardship. .

Pili, kasi ya kushughulikia miamala, ambayo itawaepusha watu na ucheleweshaji usio wa lazima.

o Secondly, the speed in processing the transactions which would spare people of unnecessary delay. .

Tatu, uwezo na umahiri wa wafanyakazi. Hili linahitajika ili kukamilisha utendaji na matokeo ya kazi.

o Thirdly, the ability and competence of the employees. This is required to perfect the performance and result of the task. .
