Knowledge of God and belief in Him constitute the very foundation of Islam. The question of God’s existence has preoccupied the great minds for many centuries. Those who believe in God seem to agree that the limited finite human intelligence cannot prove the existence of the infinite Boundless God Who is. It can only illustrate or demonstrate His existence to the satisfaction of the curious human mind. Those who deny God claim to rely on science, philosophy, or special theories of knowledge.

Their arguments are sometimes inapplicable, sometimes irrelevant, always complex, and often incomprehensible. However, the developed free mind will find its way to God. Failure to find the way does not mean that there is no way. Denial of reality does not make it unreal. The subject is so vital that it calls for a thorough and clear discussion. For the purpose of clarity some simple demonstration will be used. This may sound boring or too simple for those who already know something about the subject. Such informed persons are invited to have patience and show appreciation of the importance of the matter.

There are individuals who like to doubt the concept of God in the name of science, or because of a lack of experience and understanding. The attitude of such people reflects an uneasy mentality, although they claim to be learned intellectuals. My concern will not be with their claim; rather it will be with their true position. This will explain why a great deal of the discussion is designed in a simple shape as if it were directed mainly to children, and not to adults. On the other hand, a major objective of this work is to convey the true concept of God in Islam to the young Muslims.
