Musnad Ahmad

Bajalah says: I was the scribe of Ahnaf bin Qais’s uncle, Juz’ bin Mu’awiyah. A letter from Sayyiduna Umar (may Allah be pleased with him) reached us one year before his death, in which it was written: “Kill every sorcerer. Separate those among the Magians who have married their close relatives, and prevent them from reciting Zamzamah (the low voice recitation the Magians used to do while eating).” So we killed three sorcerers, and in the light of the Book of Allah, we began the process of separating a man from his forbidden wife. Then Juz’ once had a large amount of food prepared, placed his sword on his thigh, and invited the Magians to eat. They brought and piled up silver equal to the weight of one or two mules, and ate the food without reciting Zamzamah. Also, previously Sayyiduna Umar (may Allah be pleased with him) did not take jizyah from the Magians, but when Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) testified that the Prophet (peace and blessings be upon him) had taken jizyah from the Magians of the region called Hajar, then he also began to take jizyah from the Magians. Sufyan says that Bajalah performed Hajj with Mus’ab in the year 70 AH.
