Furthermore, Saif tries in this story to cover-up for Ziad as well, when Ziad refers to Obaid as his guardian. What is more, Saif tells the story from the time of Caliph ‘Omar, in order to make it more acceptable to Muslims. (al-Kamel of Ibn Athir — Events of the year 44 Hejri; al-Esti‘ab vol.1, pp.548-555; al-Esabah, vol.1, p.563.) The Origin of Saif's Story Saif has recorded the above story from Muhammad, Talha and Mohallab.
Saif has recorded 216 stories which are recorded in Tabari from Saif, who in turn recorded from Muhammad Bin Abdullah Bin Sawad Bin Malik Bin Nowaira, who is unknown in all history books except in Ekmal whose writer has also recorded from Saif. There are two Talhas. One is Abu Sufyan Talha Bin Abdur Rahman of whom no trace can be found. The second, Talha Bin A'lam who lived in Juan near Ray (Tehran) and Saif has not specified him in his story.
Saif has recorded sixty seven stories from Mohallab Bin Oqba al-Asadi, which also appears in Tabari, but no trace of him can be found in any biography. The story told by others apart from Saif al-Daynawari in his book The Long Stories, page 14 says: "Abu Musa considered Ziad Bin ‘Obaid, a slave of Thaqif tribe, a surprisingly ambitious and clever man, and employed him as his secretary.
Ziad was with Moghaira before that." Ibn Abdulbarr in his book al-Esti‘ab, (vol.1, p.548) says: "Before Mo'awiah offered Ziad his brotherhood he was called Ziad Bin Obaid Thaqafi." It is also written there, that Ziad bought his father Obaid and set him free which was a very good deed.
In al-Esti‘ab, page 549 from Ibn Abdulbarr it reads: "Ziad was known as Ziad Ibn ‘Obaid before joining Mo'awiah," then continues; "Ziad delivered a speech in the presence of ‘Omar the Caliph, at a party and his speech surprised every-body." One of the guests Amr'as said, "By God, if this boy (the speaker) was from the Quraish tribe he could have been the ruler." Abu Sufyan then said, " I know his origin." ‘Ali said, "Who is his father?" Abu Sufyan said, "I am." ‘Ali then said, "Stop Abu Sufyan (telling your association with Ziad's mother)." Then Abu Sufyan composed the following verse: If I was not afraid of someone (‘Omar) I should say, By God, Sakhr Bin Harb would betray, And, you ‘Ali, would certainly decide, For yourself Ziad's speech talent is from whose side.
The following historians have recorded the story of the brotherhood of Ziad and Mo'awiah: Ibn Athir in the events of the year 44 Hejri.
