The Islamic Ruling of First Cousin Marriages

The Islamic Ruling of First Cousin Marriages

My question relates to marrying first cousins. Although it’s permissible in Islam, I was wondering as regards to arguments against this as many people cite health issues and high rates of disabilities among children.

I’m struggling to get my head around a ruling in Islam that potentially puts people or children at risk. I am in no way saying the Islamic ruling is wrong as I would never oppose anything in Islam but rather I would like clarification so as to have a better understanding as non-Muslims often ask why we would have this ruling and always cite particular studies.
