The strain of al-Kray is a branch of Kuhaylan al-Krush and it originates from either the Bedouin tribe of al-‘Ajman or that of Bani Hajar.
I am really looking forward to the forthcoming publication in English of the book of King Abdallah I of Jordan, edited by his great-granddaughter Princess Alia Bint al-Hussein. The book “Jawab al-Sa’el ‘an al-khayl al-asayil” is a short treatise mainly concerned with the physical characteristics of the Arabian horse, and was already published three times in Arabic, and all three editions are now out of print.
