I notice this ‘course’ is being promoted on DeenPort:

The underlying principle of The Surrendered Wife is simple: The control women wield at work and with children must be left at the front door of any marriage to revitalize intimacy.

Hmmm…

One of the (Muslim) ‘trainers’ on this course says the following:

The [Surrendered Wife] principles essentially apply to married women of the West, which automatically excludes widows. You will find the women of the East are much more ’surrendered’ to the will of Divine decree – they bloom and thrive where they are planted rather than constantly fighting the way things are… The women of the East tend to put up with a lot more, are more hospitable and tolerant of their folk. Which is perhaps why it is more common to see thriving family systems back there.

These observations about families in the East and West appear to me to be nothing more than trite generalisations, based on zero evidence.
