Al Faleh is detained in the high-security Haer prison—where militants are held—outside Riyadh.

"Why does he deserve to go to Haer? People have a mind to think and a dream to be better," Jamila Al Ukla said.

She has sent letters to Saudi King Abdullah and the Interior Ministry. The US-based Human Rights Watch has also asked for Al Faleh's release.

"Matruk is not against the government, he is against violence. He is against radicalism and we want to fight together with the government against radicals," Ukla said.

Al Faleh was sentenced to seven years in jail in 2005 for organising a petition calling for Saudi leaders to set a timeframe for making a constitutional monarchy.
