Is an increase and development in Belief in question?
A seed grows and develops greatly until it becomes a tree; belief is like a tree too.
Islamic scholars divide belief into two levels first:
1– Taqlid (imitative) belief,
2– Tahqiq (investigative) belief
Imitative belief: It means adhering to the fundamentals of belief traditionally without reasoning on the issue as one hears from his parents, teachers and environment. Since imitative belief is a kind of believing that is not based on a detailed belief in the fundamentals and consciousness of belief, it may be exposed to some doubts and delusions and face the risk of faltering and breaking down especially in this age.
Investigative belief: It means knowing all of the issues about belief with evidence and in detail, to approve and believe without hesitation. A belief like that can protect itself from faltering and breaking down when faced by doubts and delusions.
There are various degrees of investigative belief. Islamic scholars divide those degrees into three:
1 – Certainty at the degree of knowledge: It means knowing and believing in Islamic issues scientifically and in detail.
2 – Certainty at the degree of witnessing: It means knowing and believing in Islamic issues as if seeing them or as if observing their truthfulness personally. Seeing through eyes and knowing scientifically are very different from the aspect of giving a person an idea. Man can know something definitely, without hesitation but when he sees it, his belief increases. For instance, knowing the existence of America and seeing America personally. Certainty at the degree of witnessing is believing in the fundamentals of belief as if seeing through the eyes.
3 – Absolute certainty: It means accepting and realizing the issues concerning belief by entering into them and experiencing them personally.The following example can be given to explain the three levels of belief: When smoke is seen somewhere it is known that there is a fire there. To know the presence of fire by seeing the smoke is certainty at the degree of knowledge. To go near the fire and to know the existence of fire by seeing it is certainty at the degree of witnessing. To go near the fire and to put your hand into the fire and feel the burning property of the fire and to know the existence of fire like that is absolute certainty.
