Peace, man

There’s a page discussing the Muslim greeting of “assalaamu alaykum” (peace be upon you). A snippet:

There are certain situations under which it is preferable not to offer salaam. These include; when a person is relieving himself, when one is having marital relationship, when someone is sleeping or when in the bathroom.

I can think of a number of scenarios where one would need to greet newly arrived people while “having marital relationship”, and I wouldn’t have thought any of them are exactly halal.
