They are...

They are: Ears for hearing, Eyes for seeing, Heart for understanding * * "Allah brought you out of your mothers' wombs in such a state that you knew nothing. He gave you ears and hearts, so that you may be thankful". (Surah al‑Nahl, 16:78 ) . There is another verse which says: *** *** "Then He fashioned him and breathed His Spirit into him. He has given you ears, eyes and hearts; yet you show little gratitude ". (Surah al‑Sajdah 32:9 ) .

One of the main sources of our knowledge is hearing, through which we come to know of the experience, investigations, and the ideas of others. We hear of many events from other individuals and other reliable sources. Another main source of our knowledge is seeing and observation. The third source is inner perception and comprehension.

The knowledge which is obtained through seeing, hearing and inner observation still remains superficial and has little value till it is further studied, evaluated and analyzed. This raw material must be processed in the region of heart so that it may become reliable, valuable and fit for being accepted and followed. According to the Qur'an the maturity of man depends on the correct use of these faculties. If these faculties are not used properly, man sinks to the level of animals.

"They have hearts but do not understand with them, they have eyes but do not see with them and they have ears, but do not hear with them. They are like beasts or further astray. They are heedless ". (Surah al‑A'raf, 7:179 )** . Basic and expanded role of heart The Qur'an has variously described the role of heart. Thinking, pondering and comprehending are some of its functions. Thinking means arranging the known date for the purpose of analysis, composition, comparison and evaluation.

As the result of this process, general rules and principles are obtained and then applied to particular cases. Pondering means going into the hidden aspects of the apparent phenomena in order to find the way to the real truth. What we can discover by means of our senses is only a superficial reflection of what is the present appearance of the things. Our senses can neither discover the inner truth directly, nor can they find out the ultimate end of any event.

By means of our senses we can know only what is percep­tible and observable, but they do not have enough power to have access to the inner truth. Only pondering, deep thinking and mental analysis can do that.
