I'm researching for a story set in 1045 Al-Andalus (Moorish medieval Spain) and I'm trying to discover whether historically Muslims would be prohibited by religion from working (as in commerce) on Fridays, comparable to the way Christians were prohibited from working on Sundays and Jews on Saturday.
I've Googled just about every combination of Muslim, Islam, historical, holy day, work, commerce, prohibition etc. and I still haven't found an answer.
Anyone out there have a clue?
EDIT: Answer found. Thank you very much for the help.
