Whenever I think of a "you have to do what I say" scenario, I think of movies such as Coming to America, where the prince meets his arranged wife, and the following dialogue takes place:
00:19:13 Yes, your Highness.
00:19:15 - Anything I say, you'll do? - Yes, your Highness.
00:19:19 Bark like a dog.
00:19:24 A big dog.
00:19:29 Hop on one leg.
Or Terminator 2, where John Connor requests the terminator to stand on one leg.
These frivolous, demeaning requests test the boundary of how far one is willing to go in regards to obedience. In Islam, a wife is required to obey her husband:
She is required to obey him in everything unless he commands her to do an act of disobedience. (IslamWeb)
So...
Question: Is a wife required to e.g. stand on one leg, if her husband requests it?
I would guess the immediate answer is "yes...", the husband is making a halal request, after all. Continuing "...but the husband shouldn't be making such a strange request", although the silliness of the request wouldn't exempt the wife from her obligations.
I could imagine a man requesting something absurd like this, perhaps as a kind of joke (as in the movie examples), or possibly even as a test of obedience.
Perhaps there's more to it. It may be that such frivolous, demeaning requests are another exception to the general rule.
My previous question What does being an obedient wife really mean? asks about what ordinarily and generally would be requested of a wife by her husband. This question is about a specific, hypothetical example, which is intended to explore the boundaries of Muslim marital relationships. It's a thought exercise.
