and the neighbouring districts as well; his power swelled, he routed the Caliphs’ armies, then took Rayy, cemented marital ties with the Daylam, grew ever more entrenched and formidable, and his reign lasted until he died in the month of Shaʿbān, 270 AH.

After him his brother Muḥammad ibn Zayd seized power; his rule was long, but he dealt unjustly and tyrannically until he was killed—may Allah have mercy on him—shortly before 290 AH.⦗1⦘

68 – Khālid ibn Aḥmad, the emir, Abū al-Haytham al-Dhuhli ⦗2⦘
Governor of Transoxiana. He left praiseworthy legacies in Bukhara: he honoured the hadith scholars there and gave generously to them. He asked Imām al-Bukhārī to teach the Ṣaḥīḥ in his palace so that his children might hear it, but al-Bukhārī refused; the emir took offence and expelled him from Bukhara.

Later he allied himself with Yaʿqūb al-Ṣaffār and rebelled against Ibn Ṭāhir. He performed the pilgrimage in 269 AH, was arrested, and remained imprisoned in Baghdad until he died.

He heard hadith from: Ibn Rāhwayh, ʿUbayd Allāh al-Qawārīrī, and others.

Transmitted from him: Sahl ibn Shādhawayh, Ibn Abī Ḥātim, Ibn ʿUqda, Aḥmad ibn Muḥammad al-Munkadirī, and a number of others, the last of whom was ʿAbd al-Raḥmān ibn Ḥamdān al-Jallāb.

He used to travel on foot in search of knowledge and would never ride, and he spent one million dirhams in that pursuit.

He died in 270 AH.
