Based on the work of the earlier anti-Fatimid polemicists Ibn Rizam and Akhu Muhsin, the manifesto instead put forth an alternative genealogy of descent from a certain Daysan ibn Sa'id.[4] The document was ordered read in mosques throughout the Abbasid territories, and al-Qadir commissioned a number of theologians to compose further anti-Fatimid tracts.[2] The manifesto and its list of signatories were reproduced by multiple medieval sources,[5] and during the early 20th century, due to the lack of sources that were not made available until later decades, it was used as a principal source on the origins and early history of the Fatimids.[3]
