from Ziyad (1) ibn Kusayb, who said:
“I was with Abu Bakrah beneath the pulpit of Ibn ʿAmir while he was delivering the sermon, and he was dressed in very thin garments.
Abu Bilal remarked, ‘Look at your governor wearing the clothes of profligates!’
Abu Bakrah replied, ‘Be quiet. I heard the Messenger of Allah ﷺ say: Whoever demeans the authority that Allah has placed upon the earth, Allah will demean him.’ (2)
Abu Bilal was Mirdas ibn Udayyah, one of the Kharijites.
Khalifah (3) said: In the year 29 AH, ʿUthman dismissed Abu Musa from Basra and ʿUthman ibn Abi al-ʿAs from Fars, merging both provinces under Ibn ʿAmir.
Al-Hasan narrated: Ibn ʿAmir set out on campaign with Ibn Budayl commanding the vanguard. He reached Isfahan, whose people concluded a peace treaty with him. He then advanced toward Khurasan with al-Ahnaf at the head of the army, and he conquered it—some parts by force, others by agreement.
Al-Zuhri said: Yazdegerd marched with one hundred thousand men and encamped at Marw. He appointed a man over Istakhr, but Ibn ʿAmir advanced upon it and captured the city.
He continued: Yazdegerd and those with him were killed at Marw. Ibn ʿAmir then camped at Abrashahr, where the two daughters of Chosroes resided; he besieged the city, and they sought terms of peace.
He sent al-Ahnaf on ahead, and the people of Herat concluded a treaty with him.
He dispatched Hatim (4) ibn al-Nuʿman al-Bahili to Marw, whose inhabitants also made peace. Thereafter he entered the state of ihram at Nishapur and journeyed to Mecca in gratitude to Allah.
He had previously opened Kerman and Sijistan (5).
