Who placed the sword of Chosroes where it harms him and brings him no benefit.
He then added, “Any people who have delivered this are surely trustworthy—indeed, people of integrity.
“Chosroes did nothing more than allow what he possessed to distract him from his Hereafter. He piled it up for the man who would marry his wife or marry his daughter, and he sent nothing on ahead for himself. Had he preferred his own soul and put his surplus where it belonged, it would have remained for him.”
One of the Muslims—Abū Najid (1) Nāfiʿ b. al-Aswad—said about this (2):
[light metre]
We loosed (3) upon al-Madāʾin (4) our cavalry—

The Battle of Jalūlāʾ (6)
When Chosroes—Yazdegerd son of Shahryār—left al-Madāʾin, fleeing toward Hulwān, he began along the way to gather men, aides, and soldiers from the surrounding towns. A vast multitude of Persians assembled around him, and he placed Mihran in command of them all, while he himself continued on to Hulwān (7).

Saʿd did so, sending with his nephew a sizable force—nearly twelve thousand strong—drawn from the foremost Muslims, senior Muhājirūn and Anṣār, and leading Arab chieftains. This was in the month of Ṣafar of that same year, after they had finished with the affair of al-Madāʾin.
They marched until they reached the Magians, who were entrenched at Jalūlāʾ behind their trench. Hāshim b. ʿUtbah laid siege to them. The Persians would sally forth at every opportunity, fighting with a ferocity never before witnessed. Chosroes kept sending them reinforcements, and Saʿd likewise kept sending support to his nephew time after time.
