Idara ya Usalama wa Ndani ndiyo idara inayohusika na kusimamia kila kitu kinachohusiana na usalama. Inachukua jukumu la kudumisha usalama ndani ya nchi kupitia matumizi ya jeshi la polisi. Hii ndiyo njia kuu ya kudumisha usalama. Kwa hiyo, inaruhusiwa kwa Idara ya Usalama wa Ndani kutumia polisi wakati wowote, kwa namna yoyote inayotaka, na amri zake lazima zitekelezwe mara moja. Hata hivyo, ikiwa polisi wanahitaji msaada wa vikosi vya kijeshi, ombi huwasilishwa kwa Khalifah. Yeye anaweza kuamuru Jeshi lisaidie Idara ya Usalama wa Ndani au kuipatia kikosi cha kijeshi cha kusaidia katika kudumisha usalama, au anaweza kutoa amri yoyote anayoona inafaa. Pia ana haki ya kukataa maombi hayo na kudai kwamba polisi wenyewe watekeleze kazi hiyo.

The Internal Security Department is the department responsible for administering everything linked to security. It takes charge of maintaining security within the country through use of the police force. This is the main means to maintain security. Hence, it is permissible for the Internal Security Department to use the police at any time, in any way it likes, and its orders must be implemented immediately. However, if the police require the help of the armed forces, a request is submitted to the Khalifah. He can order the Army to help the Internal Security Department or to provide it with a military force to help it in maintaining the security, or he can issue any order he sees fit. He is also entitled to refuse such requests and demand that the police carry out the task themselves.
