This books is about the lives of those Companions and Commanders who led the Islamic forces in the violent and strife-torn arenas of conflict against the Kuffar (disbelievers). They struck terror in the hearts of the enemy and the strong forts and palaces of Caesar and Chosroes trembled before their might. However, in this compilation, there are not only the stories of the battlefields but also the stories of bravery and courage, valor and piety, austerity and simplicity. These stories describe the true circumstances that led the Muslims to fight more powerful enemies than they were at that time.
