[Then the year 67 AH began]
In this year (1) ʿUbayd Allah ibn Ziyad was slain at the hands of Ibrāhīm ibn al-Ashṭar al-Nakhaʿī. The events unfolded as follows: Ibrāhīm left Kūfah on a Saturday with eight days remaining of Dhu al-Ḥijjah in the previous year; the new year dawned while he was still on the road, marching to confront Ibn Ziyad in the territory of Mosul. The two forces met at a place called al-Khāzir (2), five parasangs from Mosul. Ibrāhīm commanded eight thousand men, whereas Ibn Ziyad had forty thousand Syrians. Ibrāhīm never advanced except in full battle order.
When the armies drew near, ʿUmayr ibn al-Ḥabbāb al-Sulamī sent word: “I am with you.” He came to Ibrāhīm by night, pledged allegiance to him, and informed him that he himself held the left wing of Ibn Ziyad’s army. He promised to break and flee with his troops and said, “Do not drag the engagement out, for they are many times your number; attack at once, for they are already filled with dread of you.”
Ibrāhīm replied, “Now I know you are a sincere adviser,” and let him depart (3).
That night Ibrāhīm remained awake, his eyes never closing. Just before dawn he rose, arrayed his army and assigned its battalions (4). He led his men in the dawn prayer at its earliest time, then mounted and pressed toward Ibn Ziyad’s host, advancing slowly while he himself walked among the foot-soldiers until he reached the crest of a hill overlooking the enemy. Not a man among them had stirred; but when they caught sight of him they sprang, bewildered, to their horses and weapons.
Ibrāhīm mounted his steed and rode past the tribal standards, rousing them to fight Ibn Ziyad, declaring:
“This is the slayer of the grandson of the Messenger of Allah ﷺ. Allah has brought him to you and today has delivered him into your hands. Strike at him, for he has done to the Household of the Messenger of Allah ﷺ what Pharaoh never did to the Children of Israel. This is Ibn Ziyad, the murderer of al-Ḥusayn, who barred him—together with his children and womenfolk—from the waters of the Euphrates, prevented him from returning to his homeland, and forbade him to go to Yazīd ibn Muʿāwiyah until he killed him. (By Allah, Pharaoh never committed such a deed! Allah has now presented him to you, and I hope that Allah will heal your hearts and cause his blood to be shed at your hands.) (5)”
He then took his place beneath his banner. Ibn Ziyad advanced with his cavalry and infantry in a massive host, placing Ḥuṣayn ibn Numayr over the right wing and ʿUmayr ibn al-Ḥabbāb al-Sulamī over the left—who had already met with Ibn
