The decision was made following a hearing held amid tight security.
Zakzaky lost his left eye sight in a raid, which was carried out by the Nigerian army on his residence in the Northern town of Zaria back in December 2015.
During the raid, Zakzaky’s wife sustained serious wounds, and more than 300 of his followers, and three of his sons were killed. Sheikh Zakzaky, his wife, and a large number of the cleric’s followers have since been in custody.
The clergyman is said to have been charged with “criminal conspiracy and inciting public disturbances."
The Islamic Movement of Nigeria has called on the federal government "to listen to reason and to release Sheikh Zakzaky immediately".
