Rejoice...
Rejoice, O people of Syria, for goodness has always been with you, and there will be a tragic epic between myself and the people of Iraq!
I have seen in my vision three nights ago that a river stood between me and the people of Iraq tumultuously flowing with blood, and I tried hard to cross it, but I could not till ‘Ubaydullah Ibn Ziyad crossed it before me as I looked at him!” The Syrians shouted, “Take us wherever you wish, for our swords, with which the people of Iraq are familiar since the Battle of Siffin, are on your side.” He thanked them and distributed to them a lot of money.
He then wrote the governors of various countries informing them of the death of his father and keeping them in their jobs. He dispatched to Iraq ‘Ubaydullah Ibn Ziyad according to the advice of Serjun [Sargon], slave of his father Mu’awiyah He wrote the following letter to al-Walid Ibn ‘Utbah, governor of Medina: “Mu’awiyah was one of Allah's servants. Allah bestowed upon him generously and preferred him and granted him authority over others.
Then He took him to the world of the souls and to fragrance, to His mercy and punishment. He lived according to destiny, and he died according to a term, and he had enjoined me to beware of the descendants of Abu Turab due to their courage in killing. I have come to know, O Walid, that Allah, Glorified and Exalted is He, will seek revenge for ‘Uthman through the descendants of Abu Sufyan because they are the supporters of justice and the seekers of equity.
So, when you receive this letter, take the oath of allegiance from the people of Medina.” Then he attached a small piece of scroll wherein he wrote: “Be tough with al-Husayn, ‘Abdullah Ibn ‘Umar [Ibn al-Khattab, son of the second caliph], ‘Abdul-Rahman Ibn Abu Bakr [son of the first caliph], and ‘Abdullah Ibn al-Zubayr [a cousin of ‘Ayesha, wife of the Prophet, later on ruler of Hijaz] when you require them to swear the oath of allegiance [to me].
Whoever refuses, kill him and send his severed head to me.”[^6] The governor carried his instructions out. At mid-night, he called for al-Husayn (‘a) and [‘Abdullah] Ibn al-Zubayr in the hope that he would secure their oath of allegiance before everyone else. His messenger, ‘Abdul-Rahman Ibn ‘Amr Ibn [son of the third caliph] ‘Uthman Ibn Affan[^7] located them at the Prophet's Mosque.
