48-1 Al-Hakim Abu Ali Al-Husayn ibn Ahmad al-Bayhaqi narrated that Muhammad ibn Yahya al-Sowli quoted on the authority of Ahmad ibn Muhammad ibn Ishaq al-Khorasani that he had heard Ali ibn Muhammad al-Nowafali say, “A man from the offspring of Abi Talib had az-Zobayr swear to the truth of an issue in between the grave and the pulpit of God’s Prophet (S). Az-Zobayr swore to that and got leprosy. I saw a lot of its signs covering his legs and knees. His father also oppressed Ali ibn Musa Ar-Ridha’ (a.s.) on some occasion. Then the Imam (a.s.) cursed him. Immediately a rock fell down from some height over him and broke hisneck. And Zobayr’s father, Abdullah ibn Mos’ab, was the one who tore up the treaty of Yahya ibn Abdullah ibn Al-Hassan, insulted him in front of Al-Rashid and said, ‘O Commander of the Faithful (i.e. Al-Rashid)! Kill him. Do not spare him since this treaty is not valid.’ Yahya ibn Abdullah ibn Al-Hassan told Al-Rashid, ‘He is the one who had rebelled before along with his brother. Now he is claiming to support us.’ Then Yahya ibn Abdullah ibn Al-Hassan recited some of Abdullah ibn Mos’ab’s poems which supported Yahya’s claim. However, Abdullah ibn Mos’ab denied having authored them. Yahya challenged Abdullah ibn Mos’ab to swear to establish that he is telling the truth, and ask God for a speedy Divine chastisement in case he lied. Abdullah ibn Mos’ab did so. However, he got a fever and died after three days. His grave also collapsed several times.”The author of the book said, “This is a long tradition, but I have summarized it.”
