A--- Allah the Almighty says: {O you who believe! Obey Allah and obey the Messenger (Muhammad (Peace be upon him)), and those of you (Muslims) who are in authority. (And) if you differ in anything amongst yourselves, refer it to Allah and His Messenger ((Peace be upon him)), if you believe in Allah and in the Last Day.

That is better and more suitable for final determination}. (AnNisa', 59)

Narrated Anas Ibn Malik (May Allah be pleased with him): Allah's Messenger (Peace be upon him) says: "You should listen to and obey your ruler even if he was an Ethiopian (black) slave whose head looks like a raisin. " (Sahih Bukhari)

Narrated Ibn 'Abbas (May Allah be pleased with him): The Prophet (Peace be upon him) says: "Whoever notices something which he dislikes done by his ruler, then he should be patient, for whoever becomes separate from the company of the Muslims even for a span and then dies, he will die as those who died in the Pre-Islamic period of Ignorance (as rebellious sinners).”( Bukhari and Muslim)

'Ubadah Ibn As-Samit (May Allah be pleased with him) said: "The Prophet (Peace be upon him) called us and we gave him the Pledge of allegiance for Islam, and among the conditions on which he took the Pledge from us, was that we were to listen and obey (the orders) both at the time when we were active and at the time when we were tired, and at our difficult time and at our ease and to be obedient to the ruler and give him his right even if he did not give us our right, and not to fight against him unless we noticed him having open Kufr (disbelief) for which we would have a proof with us from Allah. "( Bukhari and Muslim)

Narrated `Abdullah: The Prophet (Peace be upon him) says: "A Muslim has to listen to and obey (the order of his ruler) whether he likes it or not, as long as his orders involve not one in disobedience (to Allah), but if an act of disobedience (to Allah) is imposed one should not listen to it or obey it." (Sahih Muslim)

He (Peace be upon him) says: "There is no submission in matters involving God's disobedience or displeasure. Submission is obligatory only in what is good (and reasonable).”(Bukhari and Muslim)

He (Peace be upon him) says: "You will listen to the Amir and carry out his orders; even if your back is flogged and your wealth is snatched, you should listen and obey.” (Bukhari and Muslim)

Allah's Messenger (Peace be upon him) says:

"One who withdraws his hand from obedience (to the Amir) will find no argument (in his defense) when he stands before Allah on the Day of Judgment, and one who dies without having bound himself by an oath of allegiance (to an Amir) will die the death of one belonging to the days of Jahillyya. " (Sahih Muslim)

Allah's Messenger (Peace be upon him) says: "Anyone who tries to disrupt the affairs of this Ummah while they are united you should strike him with the sword whoever he be. (If remonstrance does not prevail with him and he does not desist from his disruptive activities, he is to be killed.)" (Sahih Muslim)

Allah's Messenger (Peace be upon him) says: "Amirs will be appointed over you, and you will find them doing good as well as bad deeds. One who hates their bad deeds is absolved from blame. One who disapproves of their bad deeds is (also) safe (so far as Divine wrath is concerned). But one who approves of their bad deeds and imitates them (is doomed).

People asked: Messenger of Allah, shouldn't we fight against them? He replied: 'No, as long as they say their prayer.'" (Sahih Muslim) ("Hating and disapproving" refers to liking and disliking from the heart.)
