Urging obedience, and that the religion may be supported by a wicked man

It is narrated from Sayyiduna Amir bin Rabi'ah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever dies while there is no collar of obedience (ta'ah) (to the ruler of the time) upon him dies the death of the days of ignorance (mitah jahiliyyah); and whoever, after making the pledge (of allegiance), casts it off from his neck (the narrator Aswad said: 'from his neck'), will meet Allah Almighty having no excuse or argument (for what he did)."
[Musannaf Ibn Abi Shaybah: 2140]. Both teachers, Aswad bin Amir and Ali bin Hafs, narrated this narration from Sharik in the same way.

It is narrated from Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) that he said: "We used to recite (these words too, formerly): 'Allah Almighty will surely support this religion of Islam through people who will have no share (of good and reward) in the Hereafter.'"

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "One prayer until the next prayer is an expiation (kaffarah) (for the sins) between them, except for three things: associating partners with Allah (shirk), abandoning the Sunnah, and breaking the pledge." The Companions (may Allah be pleased with them) said: We know what associating partners with Allah is, but what is abandoning the Sunnah and breaking the pledge? He (peace and blessings be upon him) said: "Abandoning the Sunnah means leaving obedience (to the Muslims' authority), and breaking the pledge is that a man gives his pledge of allegiance (bay'ah) at someone's hand and then (breaking his covenant) goes out against him with a raised sword to fight him."
Imam al-Harith (may Allah have mercy on him) recorded this narration through Dawud bin al-Muhabbar, Hushaym, al-Awwam and Abdullah bin al-Sa'ib.

It is narrated from Sayyidah Umm Ayman (may Allah be pleased with her) that she heard the Messenger of Allah (peace and blessings be upon him) advising some members of his household; he (peace and blessings be upon him) said: "And never dispute with those in authority over the matter of rule and authority, even if you think that the truth is with you."
Imam Abu Ya'la (may Allah have mercy on him) narrated this same narration through Abu Bakr bin Zanjuwayh, from Abu Mushir, from Sa'id bin Abd al-Aziz.
Imam Abd bin Humayd (may Allah have mercy on him) recorded from Umar bin Sa'id, from a narrator other than Sa'id, from Imam al-Zuhri (may Allah have mercy on him), that: "The person to whom this advice was given was Sayyiduna Thawban (may Allah be pleased with him)."

It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that she asked the people who were with her: "What will be your state when two callers call: one calling to the Book of Allah, and the other calling to the authority of Allah (the authority and system of government granted by Allah)?" They said: "We will answer the call of the one calling to the Book of Allah." She said: "No, rather answer the call to the authority of Allah, for the Book of Allah is with His authority (sultan) (power and dominance)."
In the chain of this report there is an unnamed (majhul) link between the narrator Artah bin al-Mundhir and Sayyidah Umm Salamah (may Allah be pleased with her); moreover, Baqiyyah bin al-Walid is known for tadlis, so this statement is weak in its chain.

It is narrated from Alqamah bin Wa'il (may Allah have mercy on him) that he said: Sayyiduna Salamah bin Yazid (may Allah be pleased with him) asked the Messenger of Allah (peace and blessings be upon him), saying: (O Messenger of Allah,) what do you think if rulers come over us who demand their right from us (obedience and financial dues) but withhold our right from us (justice and fairness)? (On hearing this) he (peace and blessings be upon him) remained silent two or three times. Then al-Ash'ath bin Qays (may Allah be pleased with him) related this (narration), that the Messenger of Allah (peace and blessings be upon him) said (in reply): "Listen to them and obey, for upon them is the burden of what (responsibility) has been placed upon them, and upon you is the burden of what (obedience) has been placed upon you."

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: "You have been put to trial through this ruler (sultan), and he has been put to trial through you. So if he is just and fair, he will have the reward, and gratitude is due from you; and if he is unjust and oppressive, the burden of sin will be upon him, and patience is due from you."
Sahih, mawquf (authentic, stopping at the Companion).

Ishaq (may Allah have mercy on him) said: Baqiyyah bin al-Walid informed us; Thabit bin al-Ajlan narrated to us; he said: A man who had heard the like of it narrated to me, and he was one of the eminent Companions of the Prophet (peace and blessings be upon him), that the Mother of the Believers, Sayyidah Umm Salamah (may Allah be pleased with her), wrote to the people of Iraq: "Allah Almighty is free of, and He has declared His Messenger (peace and blessings be upon him) free of, whoever forms factions and separates from the community (jama'ah). So never form factions and never separate from the community. Wa al-salamu alaykum wa rahmatullah (Peace be upon you and the mercy of Allah)."
This narration is transmitted through the chain of Imam Ishaq bin Rahwayh (may Allah have mercy on him), in which this letter of Sayyidah Umm Salamah (may Allah be pleased with her) is related through a Companion of the Messenger of Allah (peace and blessings be upon him).
