When people opposed Yazeed in Madina...
When people opposed Yazeed in Madina, amongst them were the largest concentration of still living Sahaba, and the vast bulk were slaughtered. Amongst those who were martyred by the side of Husayn (as) in actual battle were also Muhammad (saws)'s sahaba, while at the actual battle not one sahaba was found on the side of Yazeed's army. Were their actions [as Sahaba] false?
Against Yazeed ranged the majority of the surviving sahaba - were all misguided waging war against a man who did not even know the Holy Prophet (saws), was a man who used his penis to penetrate men/ dogs/bears/sisters/daughters/mother? Yazeed expected the Bayya while he openly expressed that Muhammad (saws) was a fraud. Yazeed and the clique of sahaba like Abdullah bin Omar (son of the second khalifa) that supported him were scum of the worst kind.
Reply Two Ibn Kathir in al Bidaya wa al Nihaya Volume 8 page 231 narrates this hadith on the authority if Abu Ubaydah: "My Ummah shall be ruled with justice, until the first individual that shall destroy it, he shall from the Banu Ummaya, his name will be Yazeed". In a short time span of three years this Khalifah of Azam Tariq shed the blood of the family of the Prophet, the residents of Medina and catapulted the Kaaba. Rasulullah (s) pinpointed the man that would destroy the Deen BY NAME.
When this is the case then opposition to him can automatically be defined as opposition to falsehood. Why do the Nasibis support a man cursed BY NAME by the Holy Prophet (saws) himself. Reply Three Even advocate of Mu'awiya Ibn Khaldun in Mudaqqimah Volume 2 page 304 states: "Husayn was on the right path, he attained martyrdom for which he shall be rewarded".
Another Mu'awiya supporter, the Grand Sheikh of Wahabis Ibn Taymiyya states: "The Ahl'ul Sunnah believes that Husayn was a martyr and he attained an exalted rank on account of this martyrdom. Those that killed him are worthy of God's condemnation and curse".
In this connection Allamah Shibli also makes an important observation: "Husayn did not oppose giving bayya to Yazeed because he wanted to become the Khalifa - his opposition was to elevate the kalima of Tauheed and Deen of Hanafeeya, in this regards he was following the footsteps of his father". Zaynab page 157 When Imam Husayn, according the Ahl'ul Sunnah Sect, died a martyr then his difference with Yazeed cannot be condensed down to a political dispute.
