Was al-Hussenni Arafat’s father?
Distant relative, but his mentor
I've looked to see who his parents are, but they are unnamed. The only info I was able to find the Brittanica website, was that his father was a well-to-do merchant, and that his family was "related to the al-Ḥusaynī family (among its members was the grand mufti of Jerusalem, Amīn al-Ḥusaynī, a key figure of the opposition to Zionism during the British mandate)."
I would think his father would have had to have some decent connections to be a successful merchant in the 30's. Arafat was born in 1929 in Cairo, Egypt.
