I might state a few misconceptions here, but I am under the impression that Valhalla was the place where vikings that died in battle ended up. Male vikings. Norse women were not sent to raid, combat, etc. In Valhalla males had all the females that they wanted. So, I guess that I have three-part question:
What could Norse women do to live their afterlife in Valhalla?
If women could not go to Valhalla, how did the women that the men were awarded there spawn there?
How similar is the Norse mythology version of "women as an award in heaven" compared to the Islamic version?
I can't go too much in-depth right now, as I don't have the sources with me. However:
So, no, it's not comparable to Islam at all, because women aren't the reward of Valhalla. You could argue whether Valhalla is truly a reward at all. It's an honour to be in Odin's host for Ragnarök, to be sure, but it certainly isn't a(n) (after)life of leisure.
