CAIRO — He winced at the mere mention of his son’s name, visibly overcome by an unceasing thought that he struggled to articulate. He looked down to hide the tears in his eyes.
“You have to understand, I am in pain,” said Yaken Aly, choking on the words: “My son is gone.”
Mr. Aly raised his son, Islam Yaken, in Heliopolis, a middle-class Cairo neighborhood with tended gardens and trendy coffee shops, and sent him to a private school, where he studied in French. As a young man, Mr. Yaken wanted to be a fitness instructor. He trained relentlessly, hoping that his effort would bring him success, girlfriends and wealth. But his goals never materialized. He left that life and found religion, extremism and, ultimately, his way into a photograph where he knelt beside a decapitated corpse on the killing fields of Syria, smiling.
