Chapter 66 is god telling Mohammed who he can fuck. Whoop de doo. Nobody knows what it's talking about. The experts argue over it, but either he got busted for screwing his wives out of turn, or he got pissed and divorced them all but went back on his word, or he had bad breath and swore to not drink honey. (no, I didn't make up that last one. It's a hadith. srsly)
There's this handy line, useful for future business endeavors:
[66:2] Allah indeed has sanctioned for you the expiation of your oaths
Oh and hellfire. Hellfire, brother, hellfire. Lots of hellfire.
