Im not muslim. I am just reading the Quran for the first time trying to understand Islam:
...But those [wives] from whom you fear arrogance - [first] advise them; [then if they persist], forsake them in bed; and [finally], strike them. But if they obey you [once more], seek no means against them. Indeed, Allah is ever Exalted and Grand.
What does this mean by "arrogance" and why is it ok to strike your wife?
