[^3] These are...

[^3] These are: the belief in the One God (al-tawhid); the belief in resurrection on the Day of Judgement (al-ma`dd); the belief in what God has revealed to His prophets (wahy, nubuwwah). In other words, Islam answers in the affirmative to each of the fundamental questions, and considers faith in them to be the real basis of man's happiness and felicity. It undertakes the solution of life's all other problems by relying on these three basic doctrines.

In fact, it considers all solutions as the branches of a tree whose roots are these three principal beliefs. On the contrary, the materialist philosophies deny the existence of anything nonmaterial, do not believe that man has any life except this brief earthly existence, and deny the assurance held out by revelation.

Although the fundamental doctrines of the Islamic faith have been expounded and proven throughout the past centuries and on various levels, and there does not remain any doubt or uncertainty about any of them, this does not affect the basic fact that the contemporary strength of any set of beliefs hinges on two sorts of studies: one devoted to proving the validity of those beliefs, and the second, devoted to refuting contrary viewpoints. In other words, a double insight is necessary.

In the case of Islam, unless the points of disagfee­ment with other ideologies are identified, the areas that are made the targets of the opponents' criticisms and attacks are pinpointed, and a proper defence consisting of clear and logical answers is provided to the common Muslim individual, we cannot be sure of the stability of the faith on the level of the general public, and be certain of the people's steadfastness in the face of the waves of challenging ideologies.

More­over, just as in the past ideological and theological books were written in accordance with the intellectual challenges of the times and with the aim of answering their prevailing doubts, so must the ideological discussions of today be formulated in accordance with the philosophies and schools of thought now current, and with the aim of repelling their ideological attacks.
