The word yarkabun can mean riding (a horse, a bike, an elevator, etc), but also mounting (a tv on to the wall, a gopro on your helmet, a horse, etc).
When used as slang/euphemism it has the exact same sexual connotation as in English, but in theory it can also work for any type of activity where A goes/climbs on top of B, for example piggybacking or sitting on someone's shoulders (like girls at concerts), or maybe some type of pull-up like in American football.
Now, taking into account what we know:
>they were described by arabs as being extremely virile and constantly horny
>they were naked
>whatever they did lasted the whole night
>when it was over Muhammad was exhausted and in pain
Out of all the possible options, being fucked in the ass is 100% the least gay one.
Anal sex can be about physical pleasure, and being horny can sometimes push a man to be "prison gay" and make do with whatever warm hole is available. Bottoming is less defensible but there's still an element of physical pleasure (prostate stimulation and whatnot).
It's very very gay, but it's nothing compared to spending an entire night doing what is essentially a naked cuddle session, with their sweaty unwashed bodies rubbing up on each other, cocks and balls included.
There's no physical pleasure in doing this. It's exclusively for the arousal caused by your attraction to men, and even the most pent up "prison gay" man would have no reason to do this unless he's a True Homosexual, which is what the "yarkabun doesn't mean fucking" defense implies.
Every possible interpretation paints an extremely homosexual picture, especially considering that Muhammad seemingly decided to go to this meeting on his own volition.
