Sufyan narrated from "Amr that he heard Bajalah say:

I was a scribe for Jaz" bin Mu"awiyah, the paternal uncle of al-Ahnaf bin Qais. A letter came to us from ‘Umar one year before he died, telling us to execute every male practitioner of witchcraft-and perhaps Sufyan said: and every female practitioner of witchcraft - and separate all mahram couples among the Magians, and forbid them to murmur. We executed three practitioners of witchcraft, and we separated every Magian man from his wife who was forbidden to him in marriage according to the Book of Allah. He made a great deal of food, then he placed his sword on his thigh and called the Magians. They threw down one or two mule-loads of silver and they ate but they did not murmur. ʻUmar did not take the jizyah from the Magians until "Abdur-Rahman bin "Awf bore witness that the Messenger of Allah (ﷺ) had taken it from the Magians of Hajar. My father said: Bajalah did Hajj with Mus"ab in 70 AH.
