She also talked about what it meant to her and the others who escaped the kidnappers to have Malala speaking to the president.
"She makes us happy because of what she said," Ishaku said. "She goes and tell our president, 'Bring back our girls.'"
Malala to Boko Haram: 'Think About Your Sisters'
But Malala said that she not only had a message for the president, she had one for Boko Haram, if they were listening to her words.
"My simple message to Boko Haram is to think about your own sisters. ... They should understand that what they are doing is badly impacting, badly affecting the name of Islam," Malala answered. "It's not the real Islam. So they should think about their own sisters and they should release those girls. It's a request. It’s a request. Please."
But instead, Boko Haram marked the third month of the girls’ captivity by releasing a video Sunday showing its leader, Abubakar Shekau, standing in front of armored vehicles, flanked by masked militia, mocking the Bring Back Our Girls movement.
He claimed responsibility for three bombings last month, and said the schoolgirls would not be freed until the Nigerian government released the “army” of Boko Haram extremists in jail, saying sarcastically, "Oooh, bring back our army."
In the end, Malala said she believes words are stronger than armies.
She is launching a new hashtag today, #StrongerThan, celebrating the courage and sacrifice of the kidnapped girls.
"My voice and the voice of these girls here in Nigeria and the voice of the parents is more powerful than any weapon here on earth," Malala said.
"And it was our voice that defeated terrorism in Pakistan in Swat Valley and here it is going to be our voice that will defeat all the terrorist activities and all the terrorism here."
