A Saqlawiyah Jidraniyah of Ibn Zubayni of the Fid´an in the stud of Prince Ahmad Pasha Kamal, Egypt aka simply Sabha or Sobha
Notes: The above information (except for the date, which is an Al Khamsa estimate) is from the certified 1932 pedigree from the RAS for *Bint Bint Durra, which shows Sabha El Zarka as being from Ibn Zubayni. The RAS History pedigree on p12a shows her as of Ibn Zubayni´s strain from the stud of Ali Pasha Sharif.
Lady Anne Blunt [J&C 3.10.1907] refers to her as Sobha one of the original from APS Seglawi Jed.... In an earlier journal entry, upon visiting Prince Ahmad Pasha Kamal´s horses, she says the mare was about 9 years old [J&C 4.11.1891]
