Narrated Umar bin Dinar (RA):
I was sitting with Jabir bin Zaid and Amr bin Aus, and Bjalla was narrating to them in 7O A.H. the year when Musab bin Az-Zubair was the leader of the pilgrims of Basra. We were sitting at the steps of Zam-zam well and Bajala said, "I was the clerk of Juz bin Muawiyah, Al-Ahnafs paternal uncle. A letter came from Umar bin Al-Khattab (RA) one year before his death; and it was read:-- "Cancel every marriage contracted among the Magians between relatives of close kinship (marriages that are regarded illegal in Islam: a relative of this sort being called Dhu-Mahram.)" Umar did not take the Jizya from the Magian infidels till Abdur-Rahman bin Auf testified that Allahs Apostle ﷺ had taken the Jizya from the Magians of Hajar.
