It orders them to obey their legitimate rulers regardless of their appearance or backgrounds, so long as they abide by the rules and regulations of the religion in an Islamic state, or as long as these rulers are legitimate according to the constitution in a non-Islamic state. As for the Second narration, its aim is to put an end to mischief in a case where there is consensus over one individual.
Now was there a unanimous agreement over the First defendant such that the narration applies in this case? The First defendant did not obey or carry out the laws of the religion. On the contrary, he used to openly disobey and go against most of its regulations and teachings which forbid shedding of innocent blood. He did all that for the sake of securing his seat on the throne of caliphate and enjoying its pleasures. This is exactly what forced many to disagree and oppose his rulership.
As for the defense claim that what the first letter contained was only a fake threat, what is his proof for that? If they claim that the governor of Al-Madina did not obey the order due to his knowledge that it was only a fake threat that is completely false because all the books in front of you state that the disobedience of Al-Waleed ibn ‘Uqbah to the orders of the First defendant was based on personal initiative from him.
T he biggest evidence which proves that his act was seen as a disobedience by the First defendant was him being fired from his post immediately after Yazid the First defendant knew that Al-Waleed did not carry out his orders by the word. So the matter was not simply a fake threat for the sake of intimidating, as the defense claims. Rather, it was a serious decision to kill and execute immediately! And when the governor failed to carry out this orders Yazid fired him.
As for the Second letter, Ibn Abbas whom the defense attacks his integrity and claims that he was unjust, accuses people without proof, he was biased because of kinship, and he depended on assumption. The same Ibn Abbas is among the key personalities in Islam because a lot of the Islamic laws and teachings were narrated by him from the Holy Prophet (S). That is why Ibn Abbas became known as “Habr Al Ummah” / the Chief Priest of the nation.
