Who is Lady Ilya? And what is her relationship to our Master Dhul-Kifl?

Scholars have differed concerning the Prophet Dhul-Kifl mentioned in the Quran. It has been said that he is Bishr ibn Ayyub, the Prophet, peace be upon him. It was narrated that Ayyub was a prophet in the time of Ya'qub (Jacob), peace be upon him, and that his mother was the daughter of Lut (Lot), and his wife was Liya, daughter of Ya'qub. If this is true, then Lady Ilya could be the daughter of Ya'qub, the wife of Ayyub, and the mother of Dhul-Kifl. However, what is well-known is that Ayyub's wife was Rahmah, daughter of Afra'im ibn Yusuf ibn Ya'qub.
