"Aria" was 13 years old when she was sexually assaulted by imam Abdul Halim Khan , who told her he was "curing" her.
Khan, who was an imam at a mosque in east London, told young girls and their parents that they needed "healing" from "evil spirits".
After satisfying his sick appetites, he would warn his victims that if they told anyone about the abuse, the “healing” would be undone, they would be cursed, or he would harm them and their families with black magic.
"I really believed he had supernatural powers," Aria (not the victim's real name) told the BBC.
According to court documents that led to his life sentence with a minimum sentence of 20 years, Khan abused seven women and girls over an 11-year period in the same manner, with the youngest victim being just 12 years old.
As described in court, the 54-year-old imam would convince his victims to meet in secluded places such as an apartment or a car with tinted windows. There, he would rape or sexually abuse them while pretending to be... a jinn.
Khan was introduced to “Arian” by her mother when the girl started having problems at school. She told her that the imam would give her advice. But when they met, Khan told her to get in his car and “then he touched me inappropriately. I had my eyes closed and he said there would be things that would hit the car window. And I heard these hits. But I was only 13, I was terrified.”
Police became aware of the imam's actions in 2018 after the youngest victim told a school counselor about the abuse.
"Fara" met Khan as a child, after he convinced her mother that she needed treatment.
"He would make up stories, saying 'I can see things coming at you, you have to protect yourself, I have to protect your daughter,'" she told the BBC. Khan said she called the repeated sexual assaults "part of therapy."
She says the abuse “didn’t make sense to me. I said to myself, ‘this is wrong.’ I know you’re not meant to be touched that way. I was so confused, but I couldn’t go back to my family because they didn’t believe me.”
"My family didn't believe me. The people I expected to protect and support me turned their backs on me, blamed me, and continue to do so to this day," adds "Fara."
Prosecutor Melissa Garner said she had never seen anything like it before. The imam "threatened and brainwashed" his victims into believing he was possessed, she said.
Alyssa Gill, a criminology professor at the University of Bristol, who testified as a prosecution witness regarding the religious background of the case, said that while Islamic teachings do not support black magic, it still retains "significant cultural influence".
"The victims were led to believe that only Khan could protect them and their families from devastating supernatural harm and that leaving his control would expose them to devastating consequences. It is this combination of religious authority, spiritual fear and vulnerability that makes this case so special," said the criminology professor.
