Actually, the 72 virgins that martys get aren’t deceased human females. They’re houris (spirits specifically created by God for this purpose) and have the interesting property of “revirginating” after each bout without requiring surgical intervention. I’m unclear what the attraction of “popping the cherry” on an houri you’ve done a few dozen or hundred times before is supposed to be.
I’m not sure Mohammed ever stated what faithful human females were rewarded with in the afterlife. I doubt it was a big issue for him.
BTW, I believe the whole “72” bit is not from the Koran itself, but from one of the less authoritative hadiths.
