The television show was in the United States and was Deep Space Nine; Zyal was the daughter of character on the show. Her name was pronounced Zee-ahl.
I understand that a word referring or used in reference to Allah is not necessarily a name; more my explanation of the fact that I have now seen this word spelled as "Zyal" Islamic texts on the internet. I was wondering if it was an alternate name used for "Allah" or if this was some other reference used in scripture.
The other reference I saw was someone saying that Zyal was also spelled Cyal and was germanic in origin, but did not have a definition for the name/word.
