mathanxiety i would like to explain how culture is the as for misogynistic customs diet im heartened to hear that as well, in my own community alot of work is being done on FGM awareness and eradication through understanding the origins of the practise. whilst our mothers and grandmothers had it done its been nearly wiped out in my generation as globalisation of islamic fiqh occurs and people learn more from each other about history/faith/custom.
outside of Africa where FGM is practised by animists, muslims, christians, FGM is prevalent in only a few reigions of the muslim world. amongst the Kurds of Iraq and Iran, the Yemen, Malaysia, Indonesia. someone knowledgeable of the spread of the four schools of thought would recognise these countries as being followers of the Shaafiee Sunni school. one could look at that geographically and culturally disparate group of countries, see the common factor between them and say that FGM must be from islam therefore, not culture. nevermind that to wide swathes of the muslim world FGM is as abhorrent and alien to citizens of conservative Afghanisatan, Pakistan, Saudi Arabia, as it is to UK citizens. (if it is found in those countries, it is, like in the UK, because it is being practised by people who originate from countries where FGM is done eg Somalia, Yemen.) whilst acceptance and practise of male circumcision across the muslim world is nearly 100%, amongst secularists and liberals as well as the orthodox.
but delve deeper. looking at the origin of the Shaafiee school compared to the others and it is the only one that comes out of Africa, and specifically it is known as the Cairo school (whereas the Hanafi madhab is from Basra, Iraq and the Maliki madhab originated from Madinah, Arabia). this makes all the difference because the origin of FGM is pre-islamic/christian going back to the pharoanic times and was such a strong cultural custom that until recently was as much done by Egyptian Coptic Christians as by Egyptian Shaafiee muslims. much less culture of medieval Cairo. thus the backdrop to Imam Shaafiee's scholarship was this culture that permeated into the jurisprudence that when that madhab/school spread outside of africa to those kurds and yemenis and south east asian muslims it took the cultural practise of FGM with it.
