Banu Umayyah revived the custom of jahiliyah

Amputations of the head and moving the heads from one place to another, the mistreatment of the dead bodies out of sheer passion of revenge, that was prevalent during the days of ignorance (al-Jahiliyyah), started again among the Muslims during Umayyad era.

Case 1:

The very first head that was amputated from the body during the Islamic period was of Ammar Ibn Yasir (RA), the famous companion of the Messenger of Allah (PBUH&HF). Ahmad Ibn Hanbal in his Musnad narrates a tradition as follows, that has also been mentioned in the Tabaqat of Ibn Sa'd that:

In the Battle of Siffin, when the head of Ammar Yasir (RA) was cut off and was taken to Muawiyah, two people were arguing over it, each one claiming that he had killed Ammar.

Case 2:

The second head that was amputated from the body was for Umro Ibn al- Hamaq, who was among the companions of the prophet (Allah's blessings on him and his cleansed progeny). Muawiyah alleged that he has participated in the assassination of Uthman. When efforts were carried out for his arrest, he hid in a cave, where a snake bit him. The people who were in his pursuit cut off the head from the dead body and took it to Ziyad. He then sent it to Muawiyah in Damascus, where the head was roamed around the city and was finally presented to his wife in her lap.

Case 3:

The same atrocity was committed against Muhammad Ibn Abi Bakr (RA) who was the Governor for Imam Ali (AS) in Egypt. When Muawiyah captured Egypt, he was arrested and was killed. His dead body was placed in a belly of a dead donkey and then was brutally burnt.

Case 4:

After this, it became a tradition for people who sought vengeance after their enemies were killed. Imam Husain's (AS) head was amputated, and was taken from Karbala to Kufah and from Kufah to Damascus. The body of Imam Husain (AS) was brutally ruined by the running of horses.
