Obligations and limitations are often the content of Islamic law. There are things that Muslims are prescribed, with varying levels of obligation. There are certain limitations on Muslim conduct, again with varying levels of strictness and varying levels of obligation.
What must be emphasized here is that these elements of Islamic law are elements that regulate the outer shell. They do not reform the individual. They do not reform the society. Reform — change — comes from within. We cannot change our condition (for better or worse) and we cannot expect our condition to change, unless we change what is within ourselves.
Rather, the focus of the Law is stability. Thus, we seldom find Islamic legal scholars as activists in society (though there are plenty), but we very frequently find Islamic legal scholars who are quietists in society. That is the nature of the field.
Islamic law does not change you, except in your attempts to fulfill the tenets of Islamic law. Rather, Islamic law stabilizes you. When you find that there are elements of Islamic law that you struggle to fulfill, Islamic law will not provide the cure. That is outside the reach of the Law.
And Allah knows best.
