This episode is based on the "Ninth Word" in the Words by Bediuzzaman Said Nursi. 

The Ninth Word exposes some of the wisdoms in the allocation of the times of five daily prayers (salah) in a day and points out how these times mirror tremendous happenings in the life spans of each human being, humanity, the earth, and the creation.
