Every science is based on certain principles. The science of law i.e. the jurisprudence is no exception to it and Islamic Jurisprudence is more so. This world is so made that while doing something difficulties do arise. How to solve those difficulties requires a methodology. There is more than one way to do so. The easiest, the safest, the nearest, the least expensive and least time consuming solution is to be searched out. People are blessed with vision. They see and think and then propose their outlook which they consider the most practicable and fit on all available tests for a standard solution. Thus a theory or view point comes to light.
