In the background of different sciences, compiling the record of periods is very helpful to better understand and recognize rise and fall of the science. This is also applicable to Islamic jurisprudence, which is one branch of Islamic sciences. Many scholars of jurisprudence science have proposed historical periods for it. But, unfortunately, there has not been recorded any profound research work on determination for periods of comparative jurisprudence in Shi'a and Sunni works yet or at least no documents can not be found in this regard. For the first time, the present research attempts to provide five periods for comparative jurisprudence through studying historical documents and then, refers to important works written in each period of comparative jurisprudence.
