The question of scope is the question of the areas over which Islamic law is taken to have jurisdiction. Is it to be relegated to the personal aspects of ritual observance, or is it to be the law of the land, governing commerce, international relations and the criminal justice system? The question of content is the question of what the law of Islam actually prescribes.
Is the shari'ah that which was formulated by the medieval jurists, or is the interpretation of Islamic law by contemporary reformers to be accepted as being in closest conformity to the command of Allah? The questions of scope and content are often confused because would-be reformers sometimes give an interpretation of Islamic law that seems to differ very little from currently accepted secular law.
While they affirm the need to implement Islamic law, the vision of Islamic law of which they approve is closer to European civil law than to the formulations of Islamic law developed by the fuqaha. If such is one's understanding of Islamic law, the difference between the implementation of a reformed Islamic law and the replacement of Islamic law by civil law would be purely theoretical.
Of course, not all programs for the reformation of the understanding of Islamic law are to be dismissed as poorly disguised attempts to replace Islamic law by European law. There are criticisms of past interpretations of the law which arise even from within the ranks of the traditionally trained 'ulama.
Shahid Baqir Sadr, may Allah have mercy on him, for example, suggests a number of innovations to the understanding of the principles of Islamic jurisprudence (uwul al-fiqh) that have become quite influential among contemporary Shi'i jurists, but which by no means compromise with European sensibilities. Imam Khomeini, may his spirit be sanctified, also introduced a number of reforms to the understanding of Islamic law, most famously, regarding Islamic government.
The usual categorizations of Muslim thinkers into fundamentalist, modernist and occasionally, traditionalist, are misleading. A more useful approach to classification would attend to the position taken on the scope of Islamic law and the extent and kind of reform advocated within the scope that law is recognized to have.
