Hadith hurling aside, I couldn't believe that there wasn't a peep of protest when she said that. (I was shaking my head, not approving of this at all, and was ready to fall out of my chair.) Her statement sounded so fleeting and inconsequential, as if it was just another day that we could decide who deserved to be loved and who didn't.
We were taught that marriage is "half of your deen": unions between two compatible and loving people has such a big impact on how we are able to practise other aspects our religion. I've written previously about how meeting a married couple with cerebral palsy changed my idea of marriage. That while we are so caught up in our social norms of what marriage should look like (with this much money, between people of such status, that they MUST have children, that it should last forever), meanwhile there are couples who quietly defy these expectations.
Besides the tiny details of the existence of male infertility, or how a man would know his future wife is infertile, or questioning the diagnosis of fertility itself, I think it was extremely pompous of the speaker to suggest that "infertile" women are not marriageable.
Conception, pregnancy and childbirth are not exact sciences. There are many things that modern obstetrics and gynaecology don't know about or don't want to acknowledge, seeing that it's a relatively recent science dominated by white men (as almost every form of Western knowledge is). For me as a Muslim mother, and going by my first-time experiences, there are also many things that I leave to God.
Allah knows what every female carries and what the wombs lose [prematurely] or exceed. And everything with Him is by due measure. (13:8)
But apparently it's easy to be so black-and-white when it comes to deciding which women are marriageable and which are not.
