It's also sometimes used metaphorically to refer to a chapter or section, particularly in religious texts like the Quran.
Note: You might be thinking of the word "صُفْحَة" (ṣufaḥa) which refers to a platform or bench. This word is related to the word "صُفْحَة" (ṣufaḥa) for page, as both derive from the same root meaning "to be smooth or level."
