Maidah 101
If God specifies a directive the way he did in the case of divorce and inheritance it is then binding upon on all. That is why God did not do it in most of the directives. The verse you cited about burden is about misdeeds, doesn’t not apply here. Minute legislation is burdensome, it is an obvious thing. That is why God didn’t do it and what our fuqaha did is also not appreciated.
