Sabine, daughter of Mossoul and Kadidja
Below is a photo of the grey mare Sabine, foaled in 1900, who is presumably the daughter of two of M. Portalès’ imports. The picture comes from the article, ‘Les chevaux du midi’, printed in the 27 October 1907 Le Sport universel illustré.

Mossoul’s entry in volume 11 of the Stud-Book français (1894) says he was out of a Saqlawiyah, and came from the ‘Anazah.
Kadidja’s entry, in the same volume, says she was from the Mawali. Her sire was a Kuhaylan al-Kharass and her dam a Saadat; in Edouard’s post on Georges Tabet’s 1937 Ansaab al-Khayl al-Arabiyah the Sa’dan Tuqan, Sa’dan al-Hassun and Sa’dan al-Najr are all three said to be “with the Mawali”.
There are photos of Mossoul and Kadidja in two prior posts on imported stallions and mares at Pompadour.
You are right, the strain of Sa’dan Tuqan belongs to the Mawali. Even more, the Tuqan are among the historical leaders of the Mawali tribe. They Saadan strain was theirs.
Members of the Tuqan clan left the Mawali tribe and settled in Nablus, Palestine, and from there a branch moved to the Transjordanian city of al-Salt (a twin city of Nablus). One of their XXth descendants was Alia Tuqan, third wife of King Hussain of Jordan. Queen Alia died in a helicopter crash.
Another one of their descendant was Palestian poet Fadwa Tuqan.

Oh, thank you for the information on the Tuqan family and the link to the book! Did the Tuqans of Nablus and al‑Salt take their horses with them?
No ideas. The Sa’dan Tuqans must have belonged to the Tuqan branch that stayed with the Mawali. I am reading the book now (it’s in Arabic)
