Before studying the life history of Prophet Muhammad (peace and blessings be upon him), we must have a clear idea of the mission for which he worked all his life. We have to understand its true nature, scope, and features. If we scan the wide range of historical characters, we will come across great reformers, founders of philosophical systems, and great rulers and revolutionaries who changed the course of history. But the common feature of all of them is that, while they influenced only one aspect of human life, they left loopholes open for evils to creep into other aspects.
No one seemed to take any notice of this malaise, and no one provided any remedy or escape from this course. The then going overlords sank in moral degradation, and the devastating wars and frequent changes in ruling dynasties further grounded the common people under heavier strain, instead of giving any relief to them.
