In every religion there are tow things: One is the principles, i.e the beliefs and the other is Laws. The principles are restricted and concise whilst the laws are lengthy.
If you want to find out whether a religion is true or false, correct or incorrect, then the principles must be scrutinized. This is because the laws follow the principles. When the beauty of the principles have been proven, then the laws will automatically be proven to be good.
The foundational principles of Islam are three: Belief in the Oness of Allah, Belief in the Messenger-ship of all the messengers and Belief in Life after Death. All other beliefs are based on these three. The objective of this book is that all three principles are explained and clarified in such a way that it will be a means of cure and contentment for the seekers of the truth and a means of guidance for the opposition and for those in doubt.
