It may well be asked “what have we to do with this commandment that prohibits killing?!"

Such persons might think that this commandment only concerns criminals and murderers while they themselves having nothing to do with it. But, God willing, we would like to point out the importance of this commandment for everyone of us. In this book, we shall examine how this commandment may affect our lives, and whether you have ever violated it since you may have done so unconsciously.

Before we start discussing this topic we would like to explore another issue, that is God completely prohibit killing, or are there certain instances of killing which are not deemed crimes or sins, allowed by God?
