Sonita Alizadeh was only ten years old when her parents tried to sell her to a man. That attempt fell through, but it wasn't to be the last time. Now, after nine years, she has finally spoken up against the inhuman practice of selling child brides in some parts of her country, Afghanistan.

It's a unique protest, for it's in the form of a rap music video. Dressed in a veil with faux cuts and bruises on her face, she raps against this horrible practice in her music video Brides for Sale.

"I wasn’t sad then because I didn’t know what she (her mother) was talking about,' she told a BBC journalist during London’s Women in the World Summit in October 2015. “It was the first time my parents focussed on me and they bought me new clothes”, she added. Little did she know that she was going to be sold as a child bride, or that her new clothes were in fact her wedding dress.

When Sonita was eight, her family had to flee war-torn Afghanistan for Iran. When she turned 16, Sonita’s mother asked her to return to Afghanistan because her brother needed $7,000 for dowry, and the only way the family could afford it was by selling their own daughter for $9,000.

"I couldn’t breathe. I couldn’t speak", she said of learning the news. "When my mother told me they would have to sell me, my heart broke down," Sonita added. But instead of returnig to Afghanistan, she started recording her own music videos to protest against the practice of selling of child brides.

In 2014, Sonita uploaded the video Brides for Sale on YouTube, getting massive attention worldwide audience. Speaking of her country’s evil practice of selling young girls, she raps "Let me whisper, so no one hears that speak of selling girls. My voice shouldn’t be heard since it’s against Sharia."

A documentary has also been made about Sonita and about many other Afghan girls who have been victims of the horrible practice.
