A UNIQUE WISDOM IN TAHAARAT
Understand well that the example of the clothing of a person who performs salâh is like the outer skin of a fruit. The body is like the inner skin and the heart is similar to the kernel and core of the fruit.
It is obvious the object is core or kernel. Similarly the aim of this external cleanliness is to purify the heart and to make it effulgent.
Perhaps you may doubt, that how can the heart become cleansed by the cleanliness of clothing.
Therefore, understand that Allâh تعالى has kept a special relationship between the inward and outward, due to which, the effect of outward cleanliness definitely has an effect on inward cleanliness.
Judge for yourself! After completion of wudu, you will find such a feeling of purity and expansion in the heart which was not found before performing it.
It is apparent that this is the effect of the wudu which transcends the body and reaches the body and reaches the heart.
