it is reported that he would exceed all bounds in debasing ʿAlī ibn Abī Ṭālib I
and would not hesitate in cursing him.
Form 2: Ordering people to Revile him and Disassociate from him:
With the Umayyad governors the matter did not stop at merely reviling ʿAlī
I. Rather it surpassed that to instructing others to openly revile him, and to
trialling yet others by asking them to do so. They did this especially with those
people whom they thought were displeased with the Umayyad rule or whom
they assumed were the partisans of ʿAlī I.
Their insolence had reached such an extent that they even went to order some of
the Ṣaḥābah M to revile him. If they could be so bold as to do this with them
then to order others besides them was of course even easier.
Sahl ibn Saʿd I narrates:
استعمل على المدينة رجل من آل مروان،‏ قال:‏ فدعا سهل بن سعد فأمره أن يشتم عليا،‏ قال:‏ فأبي سهل،‏

فجعل رسول الله صلى الله عليه وسلم يمسحه عنه ويقول:‏ قم أبا التراب،‏ قم أبا التراب.‏
A person from the family of Marwān was appointed as the governor of
Madīnah. He called Sahl ibn Saʿd and demanded from him that he denigrate
ʿAlī I. Sahl refused. He thus said, “If you refuse to do so, then say May
Allah curse Abū Turāb.” Sahl replied, “ʿAlī did not have a name which was
more beloved to him than Abū Turāb, and he would become happy when
he was called by it.” So the governor said, “Inform us of his story, why was
he named Abū Turāb?” He responded, “Rasūl Allah H once came to
