In the face of Islam's war on humanity, it is important to note moments of courage in the face of that evil. This is part of the story of Kayla Mueller's captivity.
American hostage Kayla Mueller was tortured, verbally abused, forced into slave labor for ISIS commanders in Syria and raped by the group's top leader, but her fellow hostages say she never surrendered hope, she selflessly put the welfare of fellow captives above her own and she even stood up to executioner "Jihadi John" to defend her Christian faith.
This was one incident which demonstrated it.
In March 2014, Mueller was taken to a room next door several times where male hostages were being held. Former hostages said Emwazi paraded her in front of them to show prisoners about to be released who she was and to offer her own proof-of-life by removing her head scarf and briefly introducing herself.
Former hostage Daniel Rye Ottosen, a Danish freelance photographer, recalled how Mueller turned the tables on the men in black.
"One of the Beatles started to say, 'Oh, this is Kayla, and she has been held all by herself. And she is much stronger than you guys. And she's much smarter. She converted to Islam.' And then she was like, 'No, I didn't,'" Ottosen told ABC News.
He admits it surprised him a lot. He had once tried to strangle himself when ISIS guards strung his arms up by chains.
"I would not have had the guts to say that. I don't think so," he said. "It was very clear that all of us were impressed by the strength that she showed in front of us. That was very clear."
There was a key reason why Kayla's rapists needed her to convert to Islam.
In the Sayyaf household, Mueller went by "Kayla Carl," per the Muslim custom of referring to women with their father's name. All the girls, including Mueller, were beaten by the ISIS family — but Mueller also had to go to al-Baghdadi at night, as ABC News first reported last year.
"Baghdadi took her several times in the night for himself," Julia recounted, noting that Mueller would return later and try to not to cry, though at times she broke down.
She told the girls that part of surviving was being forced to pretend she had converted to Islam so the ISIS leader could sexually assault her, though she still clung secretly to her Christian faith.
"When she was with us, she wanted to encourage us because of also what happened with us," Julia said, noting the girls were taken in the night by ISIS men. "She was very tired every time. She was not crying every night, but she was very tired."
This is not some aberrant form of behavior. It's standard Islamic doctrine from the time of Mohammed.
