Story highlights Saudi blogger Raif Badawi was convicted of "insulting Islam" and other charges in 2014

He was sentenced 10 years in prison and 1,000 lashes

Badawi received the first 50 lashes in January, and his wife says they are set to resume soon

(CNN) A Saudi blogger convicted of "insulting Islam" is expected to receive the second 50 lashes of a 1,000-lash sentence soon, his wife says.

Blogger Raif Badawi has been behind bars since 2012 for his online posts and running a blog called "Saudi Arabian Liberals," where he hosted political and religious debate and advocated secularism in a highly religious society.

His wife, Ensaf Haidar, has said Badawi created the forum in 2008 in an effort to encourage discussion about faith.

The lashings are to be carried out 50 lashes at a time, 20 weeks in a row. Badawi received the first flogging in January 2015, but since then, the punishment has been pushed back several times.
