I'm researching several verses from the Qur'an and as it is my first time to delve into the Islamic religion I am having difficulty with some of the translations and such.

65: Divorce, verse 4, says, Pickthall, "And for such of your women as despair of menstruation, if ye doubt, their period (of waiting) shall be three months, along with those who have it not. And for those with child, their period shall be till they bring forth their burden. And whosoever keepeth his duty to Allah, He maketh his course easy for him."

But then we see...

65: Divorce, verse 4 says, Sahih International Translation, "And those who no longer expect menstruation among your women - if you doubt, then their period is three months, and [also for] those who have not menstruated. And for those who are pregnant, their term is until they give birth. And whoever fears Allah - He will make for him of his matter ease."

I've had it presented to me that this verse encourages marrying underage girls but as far as I can tell it has nothing to do with underage women but rather women undergoing menopause? Or reaching the age where they no longer experience menses.

Does this verse discuss an underage wife or simply a wife who is too old to menstruate?
