This right is simply based on the contents of the verse of the Glorious Qur'an:
O you who believe! Obey Allah, and obey the Messenger, and those charged with authority among you.
The following are some of the directives required for a Muslim to observe:
Obedience to the ruler in that which is not forbidden. This is based on the instructions of Allah's Messenger :
Listen and obey, even if a slave man from Ethiopia has been appointed [as a ruler] so long as he acts according to the Book of Allah.
Obedience of a Muslim ruler who is acting in accordance with the Divine Book of Allah is an extension to the obedience of Allah , and vice versa. Any act of disobedience to the commands of a ruler who is acting in accordance with the Book of Allah is, in reality, an act of disobedience to Allah .
A Muslim leader must be offered sincere advice, that benefits him, the community and the entire nation. A Muslim ruler must be reminded of his duties and exhorted to remain faithful to his pledge. This is based on the directives in the Glorious Qur'an:
But speak to him mildly; perhaps he may take warning or fear (Allah).
And the Prophet said: "The Religion is advice. We said: For who? He said: "For Allah and for His Book and for His Prophet and for the leaders of the Muslims and for their public.
The followers must support a Muslim ruler during crises. Muslims are commanded to comply with their leader/governor and not forsake him or provoke people against him in order to instigate troubles and evil. This is based on the instruction of Allah's Messenger ,
If a person comes to you, while a single leader is leading you, attempting to split your unity, then kill him.
