Ashqar said his father Abdel Aziz, 65, had been returning from prayers in the Old City when he was caught up in the Israeli incursion. He said his father was unarmed.
Israel said Wednesday's raid targeted two Lions' Den members, as well as a member of the Islamic Jihad group.
As young men lined up to offer their condolences on Friday, Ashqar said his father had simply been going about his everyday life and lamented the prospects of ever winning justice for him.
